Subsurface microstructure versus surface topography: Impact on the fatigue strength of stress-relieved Laser Powder Bed Fusion (L-PBF) 316L parts
Key Points
Fatigue strength is significantly affected by both subsurface microstructure and surface topography.
Microstructural differences lead to variations in fatigue performance observed in 316L parts.
Assessment using laser powder bed fusion processes to study material characteristics.
Understanding these effects may improve the performance of parts made via additive manufacturing.
