2205双相不锈钢在910～1 300℃不同的温度保温40 min后,分别进行空冷或水冷固溶处理.用金相显微镜观察了2205双相不锈钢的显微组织,测定了组织α相的含量和显微硬度.结果表明:随着固溶处理温度的升高,α相含量逐渐升高.建议2205双相不锈钢的固溶处理工艺为固溶温度1 070℃,保温40 min,水冷.
2205雙相不鏽鋼在910～1 300℃不同的溫度保溫40 min後,分彆進行空冷或水冷固溶處理.用金相顯微鏡觀察瞭2205雙相不鏽鋼的顯微組織,測定瞭組織α相的含量和顯微硬度.結果錶明:隨著固溶處理溫度的升高,α相含量逐漸升高.建議2205雙相不鏽鋼的固溶處理工藝為固溶溫度1 070℃,保溫40 min,水冷.

2205 duplex stainless steel was solid solution treated at different temperature between 910～1 300℃ heating for 40 min, then by water cooling or air cooling. The microstructure was observed by a metallographic microscope and α phase content and the hardness were tested, as well as the corrosion resistance was analyzed. The results showed that α phase rising in content gradually with the solid solution temperature increasing. We suggested that the optimized technology was heated at 1 070℃ for 40 min by water cooling.
