Room and elevated temperature fatigue crack propagation behavior of Inconel 718 alloy fabricated by laser powder bed fusion

•Room and elevated temperature FCP behavior of L-PBF IN718 was examined.•L-PBF IN718 showed higher FCP rates than CM IN718 in low and intermediate ΔK regime.•Effect of orientation on FCP behavior of L-PBF IN718 was negligible.•FCP rates of L-PBF IN718 at 650 °C were lower than those at 25 °C in low...
