In this paper, 15–53 μ m spherical powders obtained by plasma rotating electrode (PREP) and argon atomization (VIGA) were used to prepare the Inconel 718 alloy through spark plasma sintering(SPS), and then the sintered alloy was treated by solid solution and aging heat treatment. The effect of diffe...
