Design and numerical analysis of tensile deformation and fracture properties of induction hardened inconel 718 superalloy for gas turbine applications
This study examines the design and numerical analysis of induction hardened of Inconel 718 superalloys on the tensile properties. The two tensile specimens (IHT1 & IHT2)’s outside surfaces are heated to temperatures of 850 and 1000 °C. The heated samples are then quenched in oil. The samples are evaluated utilizing a 250kN capacity servo hydraulic universal test at ambient temperature and an enhanced temperature of 800 °C. At both room temperature and a raised temperature of 800 °C, the metrics yield strength (YS), ultimate tensile strength (UTS), and elongation of induction hardened sample have risen. Induction-hardened materials have better mechanical characteristics than non-induction-hardened samples, according to numerical results from ANSYS Workbench that are corroborated with experimental data. The results of the tensile test’s cracked surfaces under a scanning electron microscope (SEM) show that the presence of shallow dimple structure at 800 °C caused transgranular cleavage and intergranular dimple rupture as the modes of failure.
