高速钢其主要发展是采用了粉末冶金方法,用水或气体使熔化了的材料气化,然后将所生成的粉末用热等静压法制成钢坯。这种方法既能改善高速钢的切削性能,也能改善高速钢的磨削性能。高速钢方面其他的发展动向包括使用碳化钛,氮化钛、氮化硅和其他涂层材料。硬质合金下列生产数字可以表明在过去20年中硬质合金重要性的显著提高:1960年美国硬质合金的产量为1000公吨,1970年增加到大约4000公吨,从全世界范围来看,都有类似的发展趋势,甚至有的国家增加得更快。和
The main development of HSS is the use of powder metallurgy, gasification of molten material with water or gas, and then the resulting powder by hot isostatic pressing into billets. This method can not only improve the high-speed steel cutting performance, but also improve the high-speed steel grinding performance. Other developments in HSS include the use of titanium carbide, titanium nitride, silicon nitride and other coating materials. Cemented Carbides The following figures show a significant increase in the importance of cemented carbides over the past two decades: the production of cemented carbide in the United States in 1960 was 1,000 metric tons and in 1970 it increased to about 4,000 metric tons. From a worldwide perspective, both There are similar trends, and some countries even increase faster. with
