Abstract

Abstract: Effects of single-stage aging at 620, 650,680, 720, 750, 780 ℃ and two-stage aging at 720 ℃+650 ℃ on the microstructure and mechanical properties of GH2132 alloy were studied by means of optical microscope and microcomputer controlled electronic universal testing machine. The results show that the tensile strength and shear strength of the alloy double aging reach 1130 MPa and 720 MPa respectively, both are higher than that of the single aging. In addition, for single-stage aging within the temperature range of 620-780 ℃, with the increase of aging temperature, the tensile strength and shear strength of the alloy show a trend of first increasing and then decreasing, reach 1065 MPa and 685 MPa respectively at 720 ℃.

Key words: GH2132 alloy, aging, mechanical properties, microstructure
