Abstract

International audience; In this study, a Surface Mechanical Attrition Treatment (SMAT) is applied to a 17-4PH single edge notched tension (SENT) sample made by Atomic Diffusion Additive Manufacturing (ADAM). Grating of gold nanoparticles allowing multiscale characterizations is deposited on the surface of specimen by electron beam lithography. In-situ tensile test is carried out and images of the surface are recorded. The crack propagation is followed and the local parameters influencing the propagation are analyzed. The evolutions at the microstructure scale are compared with the macroscopic behavior of the specimen.
