摘　　要：阐述了高速钢刀具失效分析的重要性,综述了失效的主要形式,分析了主要失效原因。通过对典型的高速钢刀具失效案例分析,说明了脆断、热处理开裂和硬度不足等失效形式以及解释了原材料成分不合格、过热和脱碳等失效原因,并说明了从原材料成分、金相检验到热处理金相检验等失效分析的方法和过程。最后,总结了与失效相关的材料检验项目及检测技术和方法。The importance of failure analysis about high speed steel （HSS） cutting tools was expounded, and the main failure form was summarized. The failure mode such as brittle fracture, heat treatment cracking and insufficient hardness and so on was introduced. The failure reasons such as unqualified raw materials composition, overheating and decarburization and so on were studied. The methods and process of failure analysis from raw material composition and metallographic examination to heat treatment metallographic test were introduced. The inspection items, detection techniques and methods relating with the failure were summarized.
