摘要
2205双相不锈钢在910～1300℃不同的温度保温40rain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1070℃，保温40min，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 ot 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 rain by water eooling.
