| 摘 要： | 研究了Ｃｅ对Ｍ２高速钢凝固组织的影响及其作用机制。发现Ｃｅ在高速钢中可减轻Ｗ，Ｍｏ等合金元素的偏析，使共晶碳化物量减少并细化；Ｃｅ主要偏聚在晶界共晶碳化物与奥氏体的界面上，并有部分Ｃｅ参与形成含Ｃｅ的Ｍ２Ｃ碳化物；Ｃｅ促进共晶碳化物在高温加热时的断网和团球化。

| Abstract: | he infuences of Ce on solidification structure of M2 high speed steel were studied. The
results show that Ce has the effect of alleviating the segregation of alloy elements such as W
and Mo in high speed steel. With the addition of Ce, the amount of eutectic carbides is
decreased and the flakes of the carbides are refined. Ce mainly agglomerates on the interface
between the eutectic carbide and austenite, and a part of Ce forms M2C carbide containing Ce.
Ce can also enhance the breaking and spheroidizing of the network eutectic carbides during
high temperature heat treatment. |
