金属间化合物Fe_3Al合金抗渗碳性研究

Study on the Carburization Resistance of the Intermetallic Compound Fe_3Al

采用称重法和金相法，研究了三种成分不同的Ｆｅ３Ａｌ合金在不同表面状态下的抗渗碳性，并与１Ｃｒ１８Ｎｉ９Ｔｉ不锈钢对比，结果表明，Ｆｅ３Ａｌ合金具有很强的抗渗碳性．初步探讨了其抗渗碳机理。为Ｆｅ３Ａｌ合金在渗碳气氛中的应用提供了一定的实验与理论依据。

The carburization resistance of three kinds of be3Al alloies which have different compositions under different surface condition were studied by the weighing and metallographic method.The results show that the Fe3Al alloy has a very good carburization resistance Also,the carburizatlon resistance mechanism bas been studied,the wark stated above would provide a experimental and theoretical basis for the use of Fe3Al alloy in the carburization atmosphere.
