Effect of defocusing distance on laser powder bed fusion of high strength Al–Cu–Mg–Mn alloy
The influence of the defocusing distance on melt pool morphology, defect, microstructure and mechanical properties of the laser powder bed fusion (L-PBF) of high strength Al–Cu–Mg–Mn alloy was studied. It is found that because of the different laser energy distribution, the defocusing distance has s...
