Effect of heating scan strategy using low energy density on relief of thermal residual stress in L-PBF process for CoCrMo alloy

Effect of heating scan strategy using low energy density on relief of thermal residual stress in L-PBF process for CoCrMo alloy

This study investigates the effects of low energy density laser rescanning of Additive Manufacturing (AM) called Laser-Powder Bed Fusion (L-PBF) on the microstructure, residual stresses, and mechanical characteristics of CoCrMo alloy specimens. Specimens were fabricated under four conditions, i.e.,...
