摘　　要：研究了不同固溶处理对双相铸造不锈钢的组织及其耐蚀性能的影响。结果表明，1050℃固溶处理，使钢有适量的均匀分布的奥氏体相，钢的抗均匀腐蚀、晶间腐蚀和抗点蚀性能最好。The influence of different solid solution treatment on the structure and corrosion resistant property of cast duplex stainless steel was investigated. The results showed that a suitable amount or γphase was distributed uniformly in steel after solid solution treatment at 1050℃,thus the steel possessed best resistant properties for uniform corrosion, intergranular corrosion and pitting corrosion.
