New material development by the integration of cast technology and powder metallurgy technology-A high-performance hard material which used intermetallic compound for binder phaseHard materials made of ceramics combined with metals are used for dies and cutting tools that support high precision processing technology in Japan. Hard materials, however, need a large amount of rare metals that are scarce as resources as component and hence developing new materials with less dependence on rare metals has been expected. We developed a new hard material with Fe-Al intermetallic compound as a binder. This material was synthesized by a process combining casting and powder metallurgy and exhibited high hardness and high strength simultaneously. This paper introduces an approach to "Type2 Basic Research" in order to apply the developed material to industrial use, and a method of efficient research and development through the collaboration of researchers of different specialized fields.キーワード:超硬合金、FeAl、メカニカルアロイング、パルス通電焼結、金型、切削工具
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
