- This study was designed to examine osteoconductive effects of Mg in rats tibia. The animals were sacrificed after 1, 2, and 8 weeks. The elemental analysis was performed using SEM/EDX at week 1. Following X-ray micrography at weeks 2 and 8, samples were embedded in paraffin. The expression of osteocalcin was observed by immunohistochemical staining. The element concentrations of fibrous capsules around the specimens were also measured by ICP-MS. The concentrations of Ca and P on the surface of the Mg specimen increased in SEM/EDX. The tissue specimen showed new bone formation on the bone surface near the implanted area. The concentrations of Mg, Ca, and P were high in the fibrous capsules surrounding Mg. Implantation induced differentiation of osteoblasts, and this process was considered to be associated with new bone formation. Induction of cell differentiation may be influenced by corrosion products in addition to corroding magnesium.Mar. 2021, Dental materials journal, 40(2) (2), 498 - 507, English, Domestic magazineScientific journal

- The present study was designed to investigate the biodegradation behavior of Mg alloy plates in the maxillofacial region. For in vitro analysis, the plates were immersed in saline solution and simulated body fluid. For in vivo, the plates were implanted into the tibia, head, back, abdominal cavity, and femur and assessed at 1, 2, and 4 weeks after implantation. After implantation, the plate volumes and the formed insoluble salt were measured via micro-computed tomography. SEM/EDX analysis of the insoluble salt and histological analysis of the surrounding tissues were performed. The volume loss of plates in the in vitro groups was higher than that in the in vivo groups. The volume loss was fastest in the abdomen, followed by the head, back, tibia, and femur. There were no statistically significant differences in the insoluble salt volume of the all implanted sites. The corrosion of the Mg alloy will be affected to the surrounding tissue responses. The material for the plate should be selected based on the characteristic that Mg alloys are decomposed relatively easily in the maxillofacial region.Feb. 2019, Dental materials journal, 38(1) (1), 11 - 21, English, Domestic magazine[Refereed]Scientific journal

Today, there is a demand for bio-stapler which gradually degraded in the body and disappeared after healing from the medical field. Magnesium is noted as the material with biodegradability and biocompatibility. However, compared with the current material, magnesium have too poor mechanical properties to apply to the stapler. Therefore, it is necessary to improve its mechanical properties. It is known that addition of Ca improves the strength and corrosion resistance. To investigate the effect of alloying element on formability of Mg-Ca alloys, the generalized stacking fault energy was estimated by first-principles calculations for binary Mg-Ca, ternary Mg-Ca-Na, ternary Mg-Ca-K and ternary Mg-Ca-Sr alloys. We suggest that addition of Na, K or Sr reduced plastic anisotropy of binary Mg-Ca alloys.

- Magnesium alloys have great potential for use as structural materials since they are the lightest of all structural alloys in use. In order to use magnesium alloys in structural applications, it is important to ensure that their mechanical properties satisfy both reliability and safety requirements. One of the methods of ensuring that is to investigate the fracture toughness. However, the value of fracture toughness in magnesium alloys has been generally reported to be much lower than that in aluminum alloys. In this study, commercial Mg-Al-Zn alloys having different grain sizes, which were produced by hot extrusion, were used to examine the fracture toughness and deformed microstructures, i.e., after fracture toughness tested samples. The lower fracture toughness of magnesium alloy was related to the formation of deformation twins during fracture toughness tests.The Japan Society of Mechanical Engineers, 2007, The proceedings of the JSME annual meeting, 2007, 325 - 326, Japanese

- 生体吸収性金属材料の疑似体液中での耐食性評価の試みステントなどのデバイスは、周辺組織が修復された後には速やかに除去されるもしくは消失することが望ましい。そこで、生体内で分解・吸収される生体吸収性金属材料の開発が求められている。われわれの研究グループでは、低濃度の元素を添加した生体吸収性マグネシウム合金の開発を行っている。一方、生体内での金属材料の分解・吸収速度や安全性の評価法は確立されていない。そこで、生体外での簡便な分解速度の評価法として分極試験の適用を目指している。本研究では、これまでに開発した低濃度のAl、Y、Dyなどを含むマグネシウム二元合金を用い、溶液組成が合金の分極挙動に及ぼす影響について検討した。May 2006, 材料と環境2006講演集, 291 - 294, JapaneseInternational conference proceedings

- Improvement of tensile mechanical properties under dynamic loading is demonstrated for a commercial magnesium alloy. Ductility in magnesium is enhanced by the addition of alloying elements. Further enhancement of ductility can be achieved by the refining grain structures for the commercial magnesium alloy. The high ductility of the fine-grained alloy is owing to the absence of macroscopic cracking at mechanical twin boundaries, while the coarse-grained alloy fractured at a smaller strain owing to the stress concentration at twin boundaries. It should be expected that the fine-grained alloy exhibits the high speed impact performance during foreign object damage.The Japan Society of Mechanical Engineers, 2001, The proceedings of the JSME annual meeting, 1, 353 - 354, Japanese
- Recently, semi-solid forming has been mainly utilized for automotive components such as the brake cylider. Semi-solid forming is a metal processing technique, which is becoming of large interest owing to many inherent advantages from a view point of saving energy, comparing with conventional forging (solid state) and casting (liquid state). In spite of the feasibility of semi-solid forming, its industrial application is limited. The faster forming speed tends to be required with complicating the figuration of compacts to attain the stable formability. It is noted that the applied uniaxial strain rate to materials is 10^2〜10^3 s^<-1> during forming. Very few data are, however, available concerning with the compressive behavior of semi-solid materials at a commercial forming rate. A classical Split Hopkinson Pressure Bar was used to estimate the dynamic mechanical properties of semi-solid aluminum alloy.The Japan Society of Mechanical Engineers, 2001, The proceedings of the JSME annual meeting, 1, 365 - 366, Japanese

- Certain microstructural characteristics, such as second-phase particles, solute atoms, gain size and grain orientation, affect the impact strength of aluminum alloys. In this paper, we discuss the influence of solute magnesium atoms on impact strength and ductility. In order to investigate the influence of solute magnesium atoms, five kinds of binary Al-Mg alloys with 2∼8 wt.% magnesium concentration and high-purity aluminum were used. Dynamic tensile tests (1.5×103s-1) were performed using a Hopkinson pressure bar system, and static tests (1×10-4, 2×10-3s-1) were performed with an Instron machine for reference. The values of flow stress at certain strain can be described as a linear function of magnesium concentration beyond 2.7 wt.%. Total elongation increases with increasing strain rate and decreases with increasing magnesium concentration.The Japan Society of Mechanical Engineers, Oct. 1993, 日本機械学会論文集(A編), 59(566) (566), 2356 - 2361, Japanese, Domestic magazine[Refereed]Scientific journal
- There are certain kinds of microstructural characteristics such as second-phase particles, solute atoms, grain size and grain orientation, which affect the impact strength of aluminum alloys. In this paper we discuss the influence of distribution of second-phase particles in various commericial Al-Mg-Si system alloys. Test alloys were prepared with five kinds of heat treatment : T4, under aging, T6, over aging and O temper. The deformation behavior of these alloys was investigated using a compression test at room temperature. Dynamic tests (4×102∼2×103s-1) were performed using a Hopkinson pressure bar system, and static tests (1×10-3∼1×10-ls-1) were performed with an Instron machine for reference. It has been revealed that strain rate sensitivity of flow stress varies with the interaction between second-phase particles and dislocations.The Japan Society of Mechanical Engineers, Oct. 1993, 日本機械学会論文集(A編), 59(566) (566), 2350 - 2355, Japanese, Domestic magazine[Refereed]Scientific journal
- The deformation behavior of aluminum single crystals (99.998% purity) was investigated using a compression test at room temperature. Static tests (1×10-5∼1×10-1 s-1) were performed with an Instron machine, and dynamic tests were performed using a Hopkinson pressure bar system. The flow stress of a crystal properly oriented for double slip increases with increasing strain rate in the range of 1×10-5 to 1×10-1 s-1, while that of crystals properly oriented for single slip is independent of strain rate in the same range. Flow stress increases rapidly with increasing strain rate beyond 4×102 s-1 for all crystals. From observation with a scanning electron microscope, it is revealed that as the strain increase, the density of slip bands increases and the contrast of slip bands is weakened.The Japan Society of Mechanical Engineers, May 1993, Transactions of the Japan Society of Mechanical Engineers Series B, 59(561) (561), 1208 - 1212, Japanese, Domestic magazine[Refereed]Scientific journal

- OS0304 Deformation behavior near crack-tip in magnesiumThe effect of microstructural factor, such as grain size, on the deformation behavior near the crack tip region during the fracture toughness test was investigated using wrought Mg-Al-Zn alloy. The stress distributions related to {10-12} twinning was predicted by FEA, and the microstructural evolutions were confirmed through experiments. This type of twinning was formed at the beginning of the fracture toughness test due to the creation of a large stress field near the crack-tip region. The formation region of twinning became small with grain refinement because of the changes in the dominant plastic deformations. The results from microstructure observations showed similarities to the stress distribution from FEA. These results can be used to predict the macroscopic deformation features near the crack-tip.The Japan Society of Mechanical Engineers, 22 Sep. 2012, M&M材料力学カンファレンス, 2012, "OS0304 - 1"-"OS0304-2", Japanese
- J041015 Effect of grain boundary structure on grain boundary migration in magnesiumThe grain boundary plasticity was investigated using [1-100] symmetric tilt boundaries in magnesium through MD simulation. Grain boundary migrations occurred without any influences on grain boundary structures due to the reduction in the internal energy. On the other hands, the grain boundary structures affected the distance of grain boundary movement; the grain boundaries with high energies enhanced the grain boundary migration. The grain boundary migration was also influenced by the addition of solute atoms; the solute atoms provided stability to the grain boundary structures in magnesium, and thus, suppressing the grain boundary migration.The Japan Society of Mechanical Engineers, 09 Sep. 2012, Mechanical Engineering Congress, Japan, 2012, "J041015 - 1"-"J041015-2", Japanese

- Ductility Enhancement of Magnesium under Dynamic LoadingImprovement of tensile mechanical properties under dynamic loading has been demonstrated for a commercial magnesium alloy of AZ31. A commercial AZ31 alloy was subjected to simple shear processing through ECAE(equal-channel-angular-extrusion) followed by annealing to develop a different texture compared with the directly-extruded alloy. During the dynamic tensile test, elongation-to-failure was more than twice higher than that of the directly-extruded alloy. Inspection of the fracture surface on the dynamically deformed sample revealed that the ECAE processed alloy followed by annealing fractured with the development of ductile dimples and few macro cracks, which is often observed on the fracture surface of magnesium alloys.The Japan Society of Mechanical Engineers, 05 Nov. 2004, Materials and processing conference, 2004(12) (12), 209 - 210, Japanese

- The Effect of Accelerated Aging Temperature on Friction and Wear Properties of AZ91 AlloyIn this study, casting material of AZ91 alloys have used as test specimens. Four kinds of test specimens aging-treated at 150℃, 175℃, 225℃ and 300℃ for 100 hours were used. The effect of temperature on accelerated aging on their friction and wear properties were evaluated by a pin-on-disk tester under dry condition at room temperature. As a result, it became clear that the coefficient of friction and the wear-resistance were affected by the accelerated aging temperature.The Japan Society of Mechanical Engineers, 17 Oct. 2003, Materials and processing conference, 2003(11) (11), 239 - 240, Japanese

- Influence of Temperature and Strain Rate on Compressive Flow Stress in an AZ31 Mganesium AlloyA commercial AZ31 cast magnesium alloy was tested in compression in the temperature range from 296 K to 723 K and at strain rates of (10)^<-3>S^<-1>, (10)^<-2>S^<-1>, (10)^<-1>S^<-1> and (10)^<-3>S^<-1>. Based on the data obtained at the strain rate range from (10)^<-3>S^<-1> to 10^<-1>S^<-1>, the influence of the elevated temperature and the strain rates on the flow stress at a plastic strain of 0.1 was analyzed using the Zener-Hollomon parameter Z. The measured value of the strain rate sensitivity m varied from 0.11 at 523 K to 0.20 at 723 K. The measured value of the apparent activation energy was 144 kJ/mol.The Japan Society of Mechanical Engineers, 2003, 関西支部講演会講演論文集, 2003(78) (78), "10 - 9"-"10-10", Japanese

- 316 Enhancement of Dynamic Tensile Ductility in a Magnesium-based Composite through Controlling Its MicrostructureMechanical properties and microstructure have been investigated on a 17 vol% SiC paniculate-reinforced ZK60 magnesium-based composite (ASTM designation: ZK60/SiC/17p). The composite exhibits a high specific strength as well as a maraging steel, and limited ductility < 1%. In order to enhance the ductility under dynamic loading, additional extrusion was performed to homogenize the morphology in distributed reinforcements. It has been revealed that a homogeneous distribution of reinforcements is effective to enhance the ductility under dynamic loading.The Japan Society of Mechanical Engineers, 24 Nov. 2000, Materials and processing conference, 2000(8) (8), 119 - 120, Japanese
- 510 Effects of the Grain Size on Friction and Wear Properties of ZK60 Magnesium AlloyIn this research, wear and friction properties of a magnesium alloy have been studied in pin-on-disk under dry condition at room temperature. Used specimens are ZK60 magnesium alloys that have different grain sizes, and they are examined to investigate the influence of grain size exerted on friction and wear properties. As a result, it was proved that wear-resistance improved with increasing grain size. The coefficient of friction was about 0.3 for the coarse-grained alloy, and decreased with refining the grain structure.The Japan Society of Mechanical Engineers, 24 Nov. 2000, Materials and processing conference, 2000(8) (8), 173 - 174, Japanese

- 413 Study of improving wear resistance on magnesium alloy compositeThis paper was investigated in wear properties on ZK60 magnesium alloy, and 17vol.% SiC particle reinforced ZK60 magnesium alloy composite. And effect of SiC particle for wear resistance and wear mechanism was considered. Moreover effect of grain size was examined to improve wear resistance. The result shows that wear loss on SiC particle reinforced ZK60 magnesium alloy composite is increased due to falling of SiC particle and abrasive wear by fallen particle. It is important to enlarging grain size to improve wear resistance of magnesium alloy.The Japan Society of Mechanical Engineers, 16 Mar. 2000, 関西支部講演会講演論文集, 2000(75) (75), "4 - 19"-"4-20", Japanese

In the present study, we carried out an implantation of implants with magnesium alloy to pigs that were large enough to simulate the application to humans. As a result, biosafety, complete resorption one year after implantation, and fracture healing were confirmed, but bone resorption occurred due to the effect of gas generated during resorption, which did not occur in our previous studies using small animals. And, it was revealed that the screws would fall off, and it was confirmed again that the gas needs to be suppressed. The adverse effects of gas were not solved by devising the shape of the screw, then we tried to add surface treatment with brushite on the magnesium implants. Our results suggested that surface treatment with brushy is useful to suppress and control gas generation.

The living body safety was confirmed by in vitro cell toxicological test of a containing element and in vivo rat back subcutaneous transplantation. But the hydrogen gassing was confirmed by the absorption process. 2. Development of a bone transplantation fixed way by a biodegradablility magnesium alloy pin: A magnesium alloy pin of transplantation bone fixing (Mg pin) has been developed. It was possible to fix a bone fragment for 24 weeks by a Mg pin by an experiment of rabbit.No complications were observed in a follow up period for 6 months postoeprtively, and the healing process was excellent. Control of hydrogen gas which occurs in an absorption early stage of a Mg pin and consideration of surface design of the Mg pin seemed to be necessary.

A Mg-1.0Al alloy with a fine-grained structure was formed into plates using titanium (Ti) as a control. These plates were implanted into the subperiosteum in the head, subcutaneous tissue of the back, and in the muscle of the femur of rats for 1, 2 and 4 weeks. The Mg alloy was corroded fastest in the head, at an intermediate level in the back, and slowest in the femur. The insoluble salt deposition at the Mg alloy surface had no influence on the volume loss. Gas cavities formed around the Mg alloy at all implantation sites and decreased after 4 weeks. Histopathological examination revealed that the Mg alloy exhibited good biocompatibility, as was seen with Ti. In addition, vascularized fibrous capsules formed around the plates and became mature with time. The volume loss in the different anatomical locations correlated with capsule thickness.

To begin with, the effect of microstructural factors including grain size, texture and the existence of twins on damping capacity was clarified in pure magnesium. By controlling the microstructure of Mg-Ca alloys through thermomechanical processing, the alloy showed higher strength and damping capacity.

In subcutaneous implant model, Two magnesium alloys of different composition showed different degradation rate. Magnesium alloy of slow rate degradation revealed rapid organization of surrounded tissue. In intraosseous implant model, magnesium alloys showed similar degradation behavior to subcutaneous implant model. New bone was formed around magnesium alloys. New bone formation showed gradual increase in magnesium alloy with high rate degradation. In magnesium alloy with slow rate degradation, bone showed initial increase and afterwords gradual decrease. Magnesium alloys showed high contact rate with bone. Magnesium alloy were demonstrated the high compatibility to bone tissue.

Extraordinary inflammation was not observed even for the Mg alloy having rapid degradation rate. The local pH increase due to the OH- release accompanying the degradation may suppress cell growth when it goes over the acceptable range of cells. Coating of pure Mg with bioabsorbable medical polymers is effective to reduce initial degradation rate of pure Mg and successfully improves cytocompatibility.

In vitro, elevated activity of alkaline phosphatase was confirmed in osteoblast by magnesium ion addition. Magnesium alloy revealed the relationship between the degradation velocity and amount of gas formation. There was no pathological change in skin and bone tissue around magnesium alloy. The newly bone formation around magnesium alloy implant was seen in vivo examination. The biocompatibility and bone formation of magnesium alloy were confirmed by these results.
- Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (B), National Institute for Materials Science, 2007 - 2009Development of a High Performance Alloy-Recycling Process with Scrap Materials Including ImpuritiesWe have manufactured a small prototype casting machine for continuous casting experiments with scrap aluminum which includes impurities. We have experimented using this machine to collect basic data for establishing an ultrasonic vibration continuous casting process with Al-Si alloys, which are representative casting alloys. The techniques for controlling the solidification structures of continuous casting ingots are incomplete, and thus we further have investigated the melting temperature, cooling rate, and the shape of the molds. Moreover, by additional application of ultrasound vibration to melts flowing down on an inclined cooling horn as they pass through the liquidus line where the primary crystals appear, we have succeeded in the creation of materials with ultrafine-grained structures. It is difficult to powder aluminum alloy scraps which include a large amount of impurities such as iron, because there are problems concerning the viscosity of the melts and the degree of superheat. However, by changing the design of the nozzle which supplies the melts into an atomized gas jet, we have succeeded in the creation of powders with a mean diameter of 50μm.
