Residual stress, microstructure and micro-hardness evolution of laser powder bed fusion Ti6Al4V: Effect of stress relief annealing

Residual stress, microstructure and micro-hardness evolution of laser powder bed fusion Ti6Al4V: Effect of stress relief annealing

Stress relief annealing serves as a critical post-processing in laser powder bed fusion (LPBF) of Ti6Al4V alloy to release the inherited residual stress. However, most researches on the heat treatment of Ti6Al4V alloy in LPBF mainly focused on the high-temperature stress-relief annealing to regulate...
