高效率、高精度冲压设备的出现对模具材料相应地提出了更高的要求,因此世界各国都很重视对新材料的研究。钢结硬质合金就是近年来研制的新材料之一。钢结硬质合金按硬质相不同,分为以碳化钛和碳化钨为硬质相的两大系列。该合金与一般合金工具钢一样,可进行机械加工、热处理、焊接和锻造,同时又有近似硬质合金的高硬度和高耐磨性。钢结硬质合金以碳化钛或碳化钨为硬质相,以钢为粘结相,是以粉末冶金烧结的方法制
The emergence of high-efficiency and high-precision stamping equipment put forward higher requirements on mold materials accordingly. Therefore, all countries in the world attach great importance to the research of new materials. Steel cemented carbide is one of the new materials developed in recent years. Cemented carbide cemented carbide by hard phase is divided into two series of titanium carbide and tungsten carbide hard phase. The alloy and general alloy tool steel, can be machined, heat treatment, welding and forging, at the same time have similar high hardness and high wear resistance of cemented carbide. Carbide carbide to titanium carbide or tungsten carbide as the hard phase, steel as the binder phase is based on powder metallurgy sintering method
