Influence of mechanical attrition treatment on 17-4PH stainless steel: comparison at sub-micron scale between sent specimens produced by atomic diffusion additive manufacturing (ADAM) process
Résumé
This study focuses on the comparison between two types of single edge notched tensile (SENT) specimens made by Atomic Diffusion Additive Manufacturing (ADAM) process from Markforged Inc. The first type is submitted to Surface Mechanical Attrition Treatment (SMAT) and the second specimens are as fabricated. The deposition of gold nanoparticles (NP) at the surface, through Electron Beam Lithography (EBL), allows characterization at sub-micron scale. To observe the crack initiation and propagation, an in-situ tensile test if performed under scanning electron microscope (SEM) in order to track the NP displacements and the cracks evolution.
