Mechanical properties of Inconel 718 in additive manufacturing via selective laser melting: An investigation on possible anisotropy of tensile strength

Fabrizia Caiazzo, Vittorio Alfieri, Gaetano Corrado, Paolo Argenio

Abstract

Possible anisotropy resulting from Additive Manufacturing of metals is investigated. Superalloy Inconel 718 is considered and a number of specimens are manufactured by means of Selective Laser Melting, with different direction of growing. Tensile testing both at room and elevated temperature are conducted.
