Phase composition of the laser additively manufactured Inconel 718 alloy was investigated. The main strengthening phase of heat-treated materials conditions is gamma’ phase. δ phase deposited near Laves phase particles. Charpy impact tests show increasing of toughness in 1.5 times with the changing of building direction from parallel to transverse in as-deposited and heat-treated materials conditions. Crack propagation in the as-deposited samples is accompanied by the destruction of particles of the Laves phase and bypass them in the heat-treated material.
