Abstract

Abstract

In this paper, porous nickel-based alloys are produced using 3D printing laser melting technique. Microstructure and compressive mechanical properties of porous nickel-base alloys are studied. The results show that the porosity of the porous nickel alloy is 14.68%-18.97%, and the compressive strength is 461-535 MPa. The microstructure of porous nickel-based alloys is composed of γ-Ni dendrite. The SEM of compression fracture surface show that the fracture mode is the tearing dendrite fracture.
