固溶处理对旋压C-276合金超薄管材组织和性能影响
|
摘要
采用电子背散射衍射(EBSD)研究了固溶温度对旋压C-276合金超薄壁管材再结晶、晶界特征分布的影响;运用拉伸试验机和扫描电子显微镜(SEM)研究了固溶温度对合金力学性能及断口形貌的影响。结果表明:随固溶温度升高,完全再结晶比率上升;固溶温度为900℃时,合金未充分再结晶,完全再结晶比率为65%;固溶温度为1100℃时,完全再结晶比率达到99.4%。固溶温度高于1000℃时晶粒快速长大,固溶温度达1200℃时,平均晶粒尺寸为77.1μm。随固溶温度升高,Σ3晶界比率呈增高趋势,固溶温度900℃时,Σ3晶界所占比率为30.5%,固溶温度升高到1200℃时,Σ3晶界比率达到57.1%。固溶温度由900℃升高到1200℃,超薄壁管材室温抗拉强度R_m从1256 MPa降低到745 MPa,屈服强度R_(p0.2)从915 MPa降低到340 MPa,伸长率A_(11.3)从17.5%上升到65.5%。
The effect of solution temperature on microstructure and mechanical properties of spinning ultra-thin wall C-276 alloy tubes was investigated by electron backscatter diffraction( EBSD),scanning electron microscope( SEM) and tensile tests. Results showed that recrystallization ratio increased with solution temperature increasing. The recrystallization ratio of sample increased from 65. 0% to 99. 4% with solution temperature increasing from 900 to 1100 ℃. The grain of sample grew up quickly when solution temperature exceeded 1000 ℃. The average grain size of the alloy was 77. 1 μm after solution treatment at 1200 ℃. The results also revealed that increasing solution temperature led to an increase in the proportion of Σ3 grain boundary of sample. With solution temperature increasing from 900 to 1200 ℃,the proportion of Σ3 grain boundary of sample increased from 30. 5% to 57. 1%. Furthermore,with solution temperature increasing from 900 to 1200 ℃,the room temperature tensile strength R_m decreased from 1256 to 745 MPa,the yield strength R_(p0. 2) decreased from 1256 to 745 MPa,and elongation A_(11. 3) increased from 17. 5% to 65. 5%.
