| 摘 要： | 利用金属块样，电解萃取夹杂样，通过定量金相，扫描电镜及化学分析方法对比了Ｍ２Ａｌ和Ｍ２高速工具钢中夹杂物形态、数量、大小及分布。结果表明Ｍ２Ａｌ中由于铝的加入，使夹杂物的数量、大小及分布不均匀性都有明显的增加，夹杂物的增加主要是由铝的氧化物及其复合物的增加所致。

| Abstract: | The motphology amount,size and distribution of non-metallic inclusions in highspoed tool steeis M2Al and M2 have ben studyed by oberving the blocksample and electrolytic ex-tracting inclusion powder with quantitative microscope,SEM and chemical analyzing techniques.Itwas shown that the amount,sise and nonuniformity of distribution of inclusions all increase evi-dently because of the addition of aluminum,and the situation is caused mainly by the increase of theamount of Al2O3 inclusion and its composites. |
