What is Residual Stress in Inconel 718 LPBF about?

This study investigates the prediction of residual stress and distortion in the laser powder bed fusion (LPBF) additive manufacturing process of Inconel 718 alloy using Finite Element Method (FEM). It analyzes the effects of various laser scanning parameters and heat treatment on the residual stress and distortion of arch-shaped structures, comparing simulation results with experimental data from the literature. The findings indicate that the FEM-based simulation effectively captures the experimental data,
