Analysis of the effect of surface roughness on fatigue performance of powder bed fusion additive manufactured metals
TLDR
In this paper, the effect of surface roughness on fatigue performance of powder bed fusion additively manufactured metals was evaluated in the presence of relatively large internal defects and various microstructures, considering synergistic effect of Ra along with average critical internal defect size in combination with the stress amplitude, resulted in improved correlation of the S-N fatigue data.About:
