Quantitative Scale‐Invariant Analysis of Fracture Surface Roughness in Very‐High‐Cycle Fatigue of LPBF‐Manufactured 316L Stainless Steel
The very‐high‐cycle fatigue behavior of 316L stainless steel produced by laser powder bed fusion was investigated using a multitechnique approach combining infrared thermography, nonlinear acoustic monitoring, X‐ray computed tomography, and quantitative fractography. The primary aim of this study was to establish q...
