铸造奥氏体不锈钢CK3MCuN凝固与析出热力学模拟OA
Thermodynamic Simulation of Solidification and Precipitation of Cast Austenitic Stainless Steel CK3MCuN Based on FactSage Software
采用FactSage8.2 热力学计算软件对铸造奥氏体不锈钢CK3MCuN的平衡凝固及冷却过程相变以及基于Scheil-Gulliver冷却模式下的非平衡凝固过程展开研究.结果表明,平衡凝固过程中Fe、Ni元素易于奥氏体枝晶干偏聚,Cr、Cu、Mo、C及N元素随着凝固过程的进行易于枝晶间富集,并且Cu偏析逐渐减弱,Fe、Cr及Ni的偏析逐渐增强;非平衡凝固过程中Fe、Ni元素为负偏析,Cr、Mo、Cu、N及C为正偏析,其中Cr、Mo元素在凝固末期…查看全部>>
The equilibrium solidification and cooling phase transition of cast austenitic stainless steel CK3MCuN and the non-equilibrium solidification process in the Scheil-Gulliver cooling mode were investigated via FactSage8.2 thermodynamic calculation software.The results indicate that during the equilibrium solidification process,Fe and Ni are easily isolated by austenitic dendrites,while Cr,Cu,Mo,C and N are easily enriched in the interdendritic region.The inter…查看全部>>
