摘要:

高速鋼主要用于制造各種機床的切削刀具和軋輥材料，對我國制造業的發展意義重大。綜述了傳統鑄造法、粉末冶金法、噴射成型法和電渣重熔法制備高速鋼的研究進展，探討了4種制備方法的優缺點，重點分析了高速鋼熱處理流程（分段預處理→高溫淬火→多次回火）中各階段的主要目標、溫度和時間選擇、物相轉化、沉淀硬化和碳化物種類，提出高速鋼未來的主要制備工藝是鑄造法和粉末冶金法，并指出了對熱處理過程中碳化物的種類、溶解、析出、轉化和分布進行研究，將是未來的研究重點和方向。

Abstract:

High speed steel is mainly used to make cutting-tools of machine tools and roll materials, which is of great significance to the development of manufacturing industry in our country. The research state and prospect of processing methods for high speed steel, including conventional casting, powder metallurgy, spray-up process and electroslag remelting were summarized. And the advantages and disadvantages of four preparation processes were discussed in this paper. The close attention was paid to the main objectives, temperature and time selection, phase transformation, precipitation hardening and carbide species of heat treatment process (section pretreatment, high temperature quenching and multiple tempering) . The conventional casting and powder metallurgy are going to be the main preparation technologies for high speed steel. Moreover, the emphasis and direction for the future heat treatment process study were proposed, including the types, dissolution, precipitation, transformation and distribution of carbides.
