摘要

Abstract

Laser powder bed fusion (L-PBF) processed components usually exhibit reduced fatigue performance owing to unavoidable defects at multiple scales

especially when the loading direction is parallel to the building direction. In this study

hot isostatic pressing (HIP) was applied to the L-PBFed Al-4.74Mg-0.70Sc-0.32Zr (wt.%) alloy to enhance the fatigue properties with a focus on the defect (porosities and inclusions) effects

compared with the direct-aged samples. The results demonstrated that HIP induced inconspicuous microstructural effects

but it healed the porosities and promoted oxidation. Therefore

the fatigue crack initiation transformed the oxide-associated porosity into an oxide

with a significant fatigue strength improvement.
