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

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.
