粉末冶金法制备高速钢研究进展

Research Progress of High-Speed Steel Prepared by Powder Metallurgy

摘要: 高速钢作为一种工模具材料，具有高的强度和韧性，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，不仅能有效避免组织偏析问题，材料的力学性能和使用寿命也有所提高。本文概述了粉末冶金高速钢的发展历程，包括制粉工艺、成型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。

Abstract: As a tooling material with high strength and toughness, HSS is widely used in the manufacture of various cutting tools, moulds, rolls, wear parts, etc. By producing HSS through powder metallurgy, not only can the problem of tissue segregation be effectively avoided, but the mechanical properties and service life of the material are also improved. This paper outlines the development of powder metallurgy HSS, including the powder making process, forming process and the current situation at home and abroad, points out the current problems of powder metallurgy HSS, and outlooks its future development trend.
