Abstract

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
