Abstract

Abstract: The plate-like GH4169 alloy was prepared by 3D printing using selective laser melting (SLM), and was heat treated. The microstructure and mechanical properties of the alloy before and after heat treatment were studied by three-dimensional atom probe (3DAP) and scanning electron microscopy (SEM) with in-situ tensile techniques. The results show that both the molten pool and the grain inside of the as-printed GH4169 alloy are solidification dendrites, with a homogeneous distribution of alloying elements.After heat treatment,there are a large number of fine γ″ and γ′ precipitates formed in the matrix. The tensile test results show that after heat treatment, the 3D printed GH4169 alloy has better mechanical properties, which is attributed to the disappearance of dendrite structure and harmful δ phase reduction and a large number of nanosized γ″ and γ′ precipitates in matrix.
