摘　　要：对快凝Ｍ２＋０．５Ｂ高速钢作为刀具材料时所必须具有的性能进行了测试；借助于光学显微镜、电子显微镜、Ｘ－射线衍射仪等仪器对材料的组织和相进行了较全面的观察和分析；同时测定了淬火回火后的残余奥氏体含量，将以上各结果加以综合并进行了全面的分析和讨论。The essential performance of rapid-solidified high speed steel M_2+0.5B as a cutlery material was tested and the microstructure and phases were observed and analyzed by use of optical microscope,TEM and X-ray diffractometer. The amount of residual austenite in the steel after quenched and tempered was also determined and a comprehensive analysis and discussion about above results were made.
