摘要
该文介绍了一种特殊类型高速钢——低碳Fe-w（Mo）-co（Ni）合金的设计原理、冶炼、锻造、热处理工艺及它的基本性能，并与普通高速钢作了比较。实验结果指出，高钴含量时合金有极强的硬化能力，时效后硬度达68—69HRC，与超硬高速钢（M42）相同。该文还介绍了Fe-W（Mo）-Co（Ni）．Ti-Al合金刀具实验结果。
This paper introduces the alloying principle, forging and heat treatment processes of low-carbon Fe-W（Mo） -Co（Ni） series age hardening high-speed steels. Main properties are given and compared with those of conventional high-speed steels. Rrsults show that alloy with high cobalt content has strong age hardening ab-ility. After aging, it gives the same hardness, HRC68 - 69, as super hard high speed steel（M42）. The experimental results of the tool performance are also introduced.
