“…In the hardness Vicker's test, we test the three-dimensional (3D) printed Ti6Al4V of a bone plate, cut it to the similar dimension to the CAD model. The results from the hardness Vicker's test would be converted into MPa unit as a representative of stress numbers [21]- [22].…”

Medical applications occasionally require PSI (patient-specific implant) designs to match the implant bone’s geometry. To verify and predict failures of the design as well as a treatment before the manufacturing process, FEA (finite element analysis) is employed to simulate when given a specific number of loads. Plenty of studies have done the FEA using a couple of types of software; however, to the best of our knowledge, there is no literature to compare those several FEA results with a comparable experiment. This study further analyzes material stress, particularly to compute the VMS (Von Misses stress) of the Ti6Al4V bone plate. Furthermore, this study proposes to examine and deliver a comprehensive understanding using the four most used software of COMSOL, Ansys, Abaqus, and Autodesk Inventor. The results of those four simulations are then compared with the stress test through the Hardness Vickers test. This study will contribute significantly as a novel comparison between VMS and hardness test as a stress prediction in an implant material.

“…Recently, investigations on tensile properties have exhibited that the degradation of tensile strength by 1 mass% Ti reduction could be compensated by addition of 2 mass% Cr [21]. In addition, precipitation of Ti-CON has been identified even for V-4Cr-1Ti alloy with low interstitial impurities (C+N+O = 280 mass ppm), indicating 1 mass% Ti could maintain the scavenging effects [22]. Based on these fundamental mechanical properties and the above-mentioned specifications for the impurity levels, candidate compositions for the 10-y materials recycling are defined as Table 3.…”

Low-activation characteristics and dominant radioactive isotopes limiting materials recycling were analyzed for a fusion-reactor-grade vanadium alloy, NIFS-HEAT-2. In order to reduce contact dose rate after use in fusion reactors, purification of the base metal vanadium was examined by chemical aqueous separation, electron-beam vacuum melting and zone refining, focusing on the removal of the dominant high-activation impurities, such as Co, Cu, Fe, Nb, Ni and Mo. Based on the measured impurity levels, remote recycling of vanadium alloy is possible within ten years after use in fusion reactors under operation condition with 100 dpa irradiation. Early quasi-hands-on recycling requires further purification and re-design of alloy composition especially with low Ti and high Cr content. The present paper discusses status of material R&Ds for the ten-year recycling and impact on operation of fusion reactors.
