摘　　要：依据GB4334-2008中的不锈钢10％草酸侵蚀试验方法，研究了固溶制度对奥氏体不锈钢0Crl8Ni10Ti晶间腐蚀的影响。研究表明：0Crl8Ni10Ti的抗腐蚀性能随固溶温度的升高而降低，晶间腐蚀随保温时间的延长有加重的趋势。固溶温度在1010～1050℃时，0Crl8Ni10Ti晶粒细小，晶界上无明显的碳化物析出，晶界无腐蚀沟，耐晶间腐蚀性能好，同时可以获得良好的力学性能。The effect of solution process on intergranular corrosion of 0Crl8Nil0Ti austenite stainless steel was stud- ied based on GB 4334--2008, 10% oxalic acid etching testing method for stainless steel. The results show that the anti-corrossion property of 0Crl8Nil0Ti becomes worse with increasing solution temperature, and intergranular cor- rosion is inclined to be worse with longer holding time. When solution temperature between 1 010- 1 050 ℃, the grains are tiny without obvious carbide precipitation and corrosion line at grain boundary, as well as better intergranular property and mechemical property.
