高铬白口铸铁有优异的耐磨性能,但性脆(αK值约为2.9,4.9J/cm~2)不能承受冲击,应用范围有限。太原工业大学从金属学理论角度提出用锻造变形方法来改变共晶碳化物在基本组织中的存在形态及分布状态,从而大幅度提高其αK值及其它机械性能的目的。试锻后的高铬铸铁可以标为: αK>14.7J/cm~2;MRC>60; High chromium white cast iron has excellent wear resistance, but the brittle (αK value of about 2.9,4.9 J / cm ~ 2) can not afford the impact, the limited scope of application. Taiyuan University of Technology proposed from the perspective of metal theory using forging deformation method to change the eutectic carbide in the basic structure of the existence and distribution of state, thereby greatly improving its αK value and other mechanical properties purposes. After the forging of high chromium cast iron can be marked as: αK> 14.7J / cm ~ 2; MRC> 60;
