    Abstract:

    Utilizing Selective Laser Melting (SLM) technology, the GH3536 alloy specimens for tensile tests were fabricated by selective laser melting technology. The differences in tensile mechanical properties under different forming angles were tested. After the horizontal formed specimens were subjected to hot isostatic pressing treatment (1 175 ℃, 160 MPa, and 1 h furnace cooling), the specimens without treatment (i.e., deposited state specimens) were compared. The reasons for the changes in material properties after the treatment were analyzed. The tensile curves of GH3536 alloy with randomly distributed crystal orientations were calculated by the crystal plasticity finite element method. Combined with the VRH averaging method for the estimation results of elastic modulus, it was found that the material properties after hot isostatic pressing treatment were close to isotropic.
