Description
本発明の耐熱性合金焼結体は、WC-Co超硬合金と比較して耐熱性に優れており、さらにホウ素と窒素を内部まで均一分散させたFeAl合金またはNiAl合金の結合相を有することで、材料内部にわたり室温および600℃付近の高温における硬度、靭性などの機械的特性に優れた焼結体であることから600℃以上の高温環境下に晒される切削工具や金型などの材料として好適に利用することができる。また、WC-Co超硬合金と類似の作製プロセスを用いても高特性の耐熱性合金焼結体が作製できるため、WC-Co代替材料としての普及が期待できる。
The heat-resistant alloy sintered body of the present invention has excellent heat resistance as compared with the WC-Co cemented carbide, and further has a bonded phase of FeAl alloy or NiAl alloy in which boron and nitrogen are uniformly dispersed to the inside. Since it is a sintered body with excellent mechanical properties such as hardness and toughness at room temperature and high temperature around 600 ° C throughout the material, it can be used as a material for cutting tools and dies exposed to high temperature environments of 600 ° C or higher. It can be preferably used. Further, since a heat-resistant alloy sintered body having high characteristics can be produced by using a production process similar to that of WC-Co cemented carbide, it can be expected to be widely used as a substitute material for WC-Co.
