Existing Form of Co in 0Cr18Ni9 Stainless Steel and Its Effect on Phase Composition
摘 要
采用真空感应炉冶炼了不同钴含量的0Cr18Ni9不锈钢, 结合显微组织、物相组成和电子探针成分分析, 研究了钴元素的存在形式及对铸态不锈钢各相点阵常数及相组成的影响。结果表明: 在0Cr18Ni9不锈钢中钴主要以固溶形式存在于奥氏体和δ铁素体中, 在奥氏体中的含量高于在δ铁素体中的; 钴的存在使奥氏体和δ铁素体的点阵常数都增大; 随着不锈钢中钴含量的增加, δ铁素体数量减少; 奥氏体的点阵常数随δ铁素体数量的减小而增大。
Abstract
0Cr18Ni9 stainless steel with different Co contents was smelted by vacuum induction furnace. The effect of existing form of Co on lattice constant of phases and phase′s composition was studied by combining with microsture, phase composition and electron probe analysis. The results show that Co in 0Cr18Ni9 stainless steel mainly existed in the austenite and ferrite in the form of solid solution, the content of Co in the former was more than in the latter. Co could increase the lattice constant of austenite and δ ferrite. The number of ferrite reduced with increase of Co content in stainless steel. The lattice constant of austenite increased with decrease of the number of ferrite.
