| Abstract: | Based on the theory that Fe based cast alloys with two phase structure of metastable austenitic matrix M\-7C\-3 eutectic carbide have good wear resitance and impact toughness,this paper exploited Fe C Cr Mn system wear resisting alloys with metastable austenite matrix.In the sliding abrasion test,the wear resistance of the test alloys was better than that of Cr25 white cast iron with martensite matrix and much higher than that of Mn13 cast steel as a traditional wear resisting material.Its high wear resistance partially attributed to the ability of abrasion induced martensite transformation which increased the hardness of the matrix surface layer rapidly.The adoption of the systematic alloys is of great significance in energy saving. |
