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.
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.
