摘要

通过三种变质剂对低合金白口铸铁进行了变质处理及热处理,从金相、硬度、冲击韧性等各方面进行了分析研究。结果表明:低合金白口铸铁可以通过变质处理来改变组织形态和分布,增强基体的连续性,提高材料的韧性;其中Zn+Ca-Si+Nb变质剂的变质效果最好,变质处理后再进行正火处理,能进一步改善性能。

Abstract

By modification and heat treatment,analyzed from all aspects of microstructure,hardness and impact toughness through three kinds of modifiers for low-alloy white cast iron. Experimental results showed that modification could change the morphology and distribution of low alloy white cast iron,it also could enhance that’s continuity of the matrix and the toughness of the material,and the Zn + Ca-Si + Nb modification have the best effect,normalizing treatment after modification can further improve performance.
