变质处理对低铬白口铸铁组织和性能的影响

Effect of Modification on Structure and Properties of White Cast Iron With Low Chromium

研究了1#稀土硅铁合金、钛铁、钒铁、金属碲对低铬白口铸铁金相组织及力学性能的影响。结果表明,经优选的复合变质剂处理的白口铸铁晶粒细化,冲击韧度有较大的提高。

An effect of 1~# RE,Ti-Fe,V-Fe and Te on the matrix structure and mechanical properties of white cast iron containing low-chromium was studied.The results show that the impact toughness of white cast iron is improved and the grain is refined after the modification.
