摘要
采用金相显微镜（OM）、扫描电镜观察（SEM）、X射线衍射（X—Ray）分析及力学性能测试等研究手段，研究了不同固溶温度对某种新型铸造双相不锈钢组织及力学性能的影响。结果表明：在950—1050℃温度区内固溶处理后，合金的强度、硬度和延伸率随固溶温度的升高而逐渐增大；随着固溶温度的升高，合金的断口形貌从解理断裂逐渐转为准解理断裂。
The microstructure and mechanical property of a new kind of cast duplex stainless steel after different solution treatment were studied by using optical microscope（OM）, scanning electron microscope（SEM）, X-ray diffraction and mechanical property testing. And the fracture modes under different solution treatment were analyzed. The results show that when the alloy is solution-treated in the range of 950- 1 100℃, The strength,hardness and plasticity of alloy are improved with the increase of solution temperature, at same time, fracture mode will change from cleavage to quasi-cleavage.
