Mechanical And Material Properties Of Castings Produced

Superior creep strength of a nickel-based superalloy ...

Abstract The creep properties of a polycrystalline nickel-based superalloy produced via selective laser melting were investigated in this study. All heat treatment conditions of the additively manufactured material show superior creep strength compared to conventional cast and wrought material. The process leads to a microstructure with fine subgrains.
