When carburized under high carbon potential (1. 1% C), microcracks tend to appear on the martensiticmatrix near the outer surface of the layer.
表面碳势为1.1%C的渗碳硬化层内,临近外表面部位的枣核马氏体中会出现显微裂纹。

However, the martensiticmatrix of high-chromium cast iron has excellent abrasion-resistant tissues, which used to be obtained only by means of heat treatment.
具有马氏体基体的高铬铸铁,有理想的耐磨组织,但通常要通过热处理才能得到。

The influence of carbon in martensiticmatrix (by use different austenizing temperature) on two body abrasive and impact-abrasive wear resistance of ductile iron is studied.
