金属粉末射出成形法によるTi基硬質焼結材料の開発 Development of Sintered Titanium Base Hard Alloy by Metal Injection Molding
Ti-Mo alloys have difficulties in manufacturing by melting-casting process because of its heavy gravitational segregation. On the other hand, several types of sintered titanium base hard alloys such as Ti-Mo and Ti-Mo-TiC have been developed by the powder metallurgy (P/M) process. However, there are still problems in fabricating three dimensional complex shaped components by conventional P/M process. Metal injection molding (MIM) process may solve those P/M processing problems because of the near net shape forming with high density and high performance properties.<BR>In this study, the effects of MIM processing conditions (debinding, sintering) on the mechanical properties and microstructures of sintered titanium base hard alloys were investigated. Injection molded Ti-Mo-TiC alloys showed the same microstructures and mechanical properties as those of conventional P/M alloys. This indicates that MIM process has enormous potential to produce several types of high performance sintered titanium base hard alloys.
