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机械性能的影响。结果表明经过变质处理的白口铸铁晶粒细化 ,冲击韧性有较大的提高
The effects of 1 # rare earth ferrosilicon alloy, ferrotitanium, vanadium iron and tellurium on microstructure and mechanical properties of low chromium white cast iron were studied. The results show that after the deterioration of the white cast iron grain refinement, impact toughness has been greatly improved
