提出一种用于铸造链链节使用的稀土变质处理高强铸钢材料。研究了此材料的成分设计、金相组织、材料处理。通过分析表明,这种由稀土变质与热处理的复合作用构成的材料组织具有高强度铸钢材料性能,可作为铸造链链节的替代材料应用。
A rare earth modified high strength cast steel used for casting chain link is proposed. The composition design, microstructure and material processing of this material were studied. The analysis shows that this kind of material structure composed of the compound effect of RE modification and heat treatment possesses the properties of high strength cast steel and can be used as an alternative material for cast chain link.
