Abstract

The paper investigates the influence of the layer thickness and the laser spot diameter in the process of selective laser melting, as well as subsequent heat treatment on the structural-phase composition and mechanical properties of the manufactured parts. The possibility of manufacturing parts with a tailored structure from an Inconel 718 superalloy using selective laser melting is demonstrated by varying the technological parameters of the process. In this case, the elements of a part with different grain size and orientation are formed.

Keywords: Selective Laser Melting, Inconel 718, nickel superalloy, powder metallurgy, additive manufacturing
