摘要: 分析测试了GH3230合金氩弧焊接后经不同焊后热处理制度处理后的显微组织、显微硬度和拉伸性能。试验结果表明:GH3230合金焊接板材经1140~1180 ℃保温10 min焊后热处理,既能使焊后残余应力得到充分释放,又能保证组织稳定,满足合金力学性能要求。

关键词: GH3230合金, 焊后热处理, 残余应力, 组织

Abstract: Microstructure, microhardness and tensile properties of argon arc welded GH3230 alloy after different post weld heat treatment(PWHT) were tested and analyzed. The results indicate that after PWHT at 1140-1180 ℃ for 10 min, the GH3230 alloy can not only release the residual stress caused by welding, but also ensure the stability of microstructure, which meets the mechanical requirements of the alloy.

Key words: GH3230 alloy, post weld heat treatment, residual stress, microstructure
