| 摘 要： | 采用过流冷却体法制备了过共晶高铬铸铁,主要研究过流冷却体表面形状和倾斜角度对过共晶高铬铸铁中初生M7C3型碳化物形貌及尺寸的影响。结果表明:表面凹槽半径较大的过流体制备的初生M7C3型碳化物更细小、圆整;在较大倾斜角时,两种不同表面形状的过流冷却体制备的初生M7C3型碳化物的形貌及尺寸与较小倾斜角制备的相比,前者的差异更明显。

| Abstract: | A hypereutectic high chromium cast iron was prepared by inclined cooling plate method,and the effects of surface shape and inclination angle of inclined cooling plate on morphology and size of primary M7C3 carbides in hypereutectic high chromium cast iron were studied.The results show that the primary M7C3 carbides prepared by the inclined cooling plate with bigger groove radius were more finer and rounder.The difference of morphology and size of primary M7C3 carbides prepared by inclined cooling plate with different surface shapes at bigger inclination angle were more obvious than those of being prepared at smaller inclination angle. |
