Inconel 718 (L-PBF, solution treated 980 °C)

UNS N07718

Inconel 718 made by laser powder bed fusion and then solution treated at 980 °C is a niobium-strengthened nickel-chromium-iron superalloy in a sub-solvus annealed state. As built, it has fine columnar cellular-dendritic grains along the build direction, niobium-rich segregation, high residual stress and direction-dependent properties. The 980 °C treatment relieves much of the stress and partly dissolves the segregation while leaving the columnar grains largely unrecrystallized, and it prepares the part for a later aging step. Parts are used for turbine and combustor hardware and other complex high-temperature components in aerospace and energy.
