【摘要】 以 Fe-C-Cr三元合金相图分析了不同成分的铬系白口铸铁的凝固过程 ,阐述了三相共晶及四相包共晶反应对其微观组织的影响。通过试验对比 ,提出了合金元素对铬系白口铸铁微观组织的影响主要是通过对其三相共晶及四相包共晶反应过程的影响而产生更多还原

【Abstract】 The solidiffication of different chromium white cast iron is analyzed with Fe-C-Cr metastable system in this paper, and the effects of eutectic and quasi-peritectic equilibrium on microstructures are studied. According to experiment, the effects of alloy elements on the microstructures of chromium white cast irons are fulfiled through their effects on the eutecrtic and quasi-peritectic equilibrium.\;更多还原
