摘　　要：高速钢作为一种工模具材料,具有高强度和高韧性,被广泛用于制造各种切削工具、模具、轧辊、耐磨件等。通过粉末冶金法生产高速钢能从根本上避免液相烧结过程中成分不均匀带来的组织偏析及粗大网状碳化物问题,其制品更具有晶粒细小、力学性能优异、使用寿命长等特点。本文概述了以粉末冶金法生产高速钢的一般工序及发展历程,包括制粉工艺、成形工艺和国内外发展现状,指出了目前粉末冶金高速钢存在的问题,并对其未来的发展趋势进行展望。As the tooling materials with high strength and toughness,the high speed steels(HSS)are widely used in the manufacture of cutting tools,moulds,rolls,and wear parts.The production of HSS by powder metallurgy not only avoids the problems of segregation and the formation of coarse reticulated carbides caused by inhomogeneous composition in the liquid phase sintering process,but also provides the products with fine grain size,excellent mechanical properties,and long service life.The general process and development of the HSS production by powder metallurgy were summarized in this paper,including powder making,forming,and the current development status at home and abroad,the problems of the current powder metallurgy HSS were pointed out,and the future development trend was prospected.
