| Outline of Final Research Achievements |
Aiming to develop functionally gradient bacteriostatic alloys, we prepared experimental Ti-Ag alloys and investigated their machinability. The machinability of Ti-Ag alloys was superior to that of pure titanium. On the other hand, experimental Ti-Nb-Cu ternary alloys were prepared and investigated their properties. The differences in the mechanical properties are attributable to solid-solution strengthening or to precipitation strengthening by the dual-phase (alpha + beta) structure. Additionally, we developed a simplified fixating device for performing intraoral radiography in beagle dogs.
