刃具钢结硬质合金是一种界于硬质合金与高速工具钢之间的新工具材料,被称为一种可机械加工的硬质合金。它和硬质合金一样,具有良好的耐磨性、刚性和红硬性,而又能象高速工具钢一样具有可热处理、可机械加工和焊接的性能。这种材料是用真空粉末冶金方法制成的。它采用一种极高显微硬度的碳化钛(TiC)作硬质相,用高速工具钢作粘结相和合金的基体,碳化钛硬质相使这一材料具有硬质合金的一些优点,而高 Cutting Tool Steel Carbide is a new tool material between cemented carbide and high-speed tool steel, known as a machinable carbide. Like cemented carbide, it has good abrasion resistance, rigidity and red hardness, but is as heat-treatable, machinable and weldable as high-speed tool steels. This material is made by vacuum powder metallurgy. It uses a very high hardness of titanium carbide (TiC) as a hard phase, high-speed tool steel for the binder phase and alloy matrix, titanium carbide hard phase makes this material has some advantages of cemented carbide, and high
