摘要/Abstract

摘要： 通过Thermo-Calc热力学计算软件制定含Cu超级奥氏体不锈钢的固溶处理温度为1000~1200 ℃,保温60 min。通过光学显微镜、SEM与EDS研究了固溶温度对含Cu超级奥氏体不锈钢显微组织、析出相和夹杂物的影响,研究结果发现Cu能促进试验钢的再结晶及析出相的溶解,在1000 ℃以上固溶处理时析出相均为σ相。试验钢的夹杂物类型主要是镁铝氧化物和硫化物。确定1200 ℃为微Cu试验钢的最佳固溶处理温度。

关键词: 超级奥氏体不锈钢, Cu, 固溶处理, 析出相, 夹杂物

Abstract: According to Thermo-Calc thermodynamic calculation software, the solution temperature of the copper-containing super austenitic stainless steel was drawn up between 1000-1200 ℃, and the holding time was 60 min. The influence of solution temperature on microstructure, precipitated phase and inclusion of the copper-containing super austenitic stainless steel was studied by means of metallography microscope, SEM and EDS. The results show that Cu can promote the recrystallization and precipitated phase's dissolution of the tested steel, and the precipitated phase is σ phase when solution treated at above 1000 ℃. The inclusions in the tested steel are mainly magnesium aluminum oxides and sulfides. It is determined that the best solution treatment temperature of the tested steel with trace Cu is 1200 ℃.

Key words: super austenitic stainless steel, Cu, solution treatment, precipitated phases, inclusions
