312 改性对高铬铸铁热处理显微结构的影响 为了提高元件的耐磨性需要在具有高韧性的基体结构与高铬铸铁中的硬碳化物之间的协调 。然而浇铸时材料的显微结构并不能满足这一要求。因此必须通过热处理的方法改善基体的显微结构和碳化物的形态 、尺寸、质量和分布这样可以
312 Effects of modification on the microstructure of high chromium cast iron heat treatment In order to improve the arasion resistance of components the coordination etween matrix structure with high toughness and hard carides in the high chromium cast iron is required However the microstructure of ascast materials cannot meet this requirement Therefore it is necessary to improve the microstructure of the matrix and the morphology size quantity and distriution of carides y means of heat treatment which can take full advantages of the arasion resistance of the material The metallographs shown in Figs 2a and 2 are the microstructures of heat treated high chromium cast iron modified with 0 RE 0 V 03 Ti and 01 B and 08 RE 04 V 03 Ti and 01 B respectively It can e oserved that the morphology of carides is almost unchanged after heat treatment ut the size of carides is further reduced and the isolated degree of caride is increased
