Abstract
Advanced characterization at the nanoscale of Co-Cr-Mo-W, and Ti6Al4V alloys produced by Laser Powder Bed Fusion (LPBF) has been carried out in order to investigate the structural features responsible of the material performances. The alloys considered in this study are key materials in advanced field such as aerospace, automotive and biomedicine, while LPBF is becoming the reference for fabrication of metal parts by additive manufacturing (AM). Combining advanced metallic materials with innovative production technologies results in unexpected mechanical properties of final products. In this study, several characterization techniques including scanning (SEM) and transmission (TEM) electron microscopy, X-ray diffraction (XRD) and neutron-based techniques have been used to investigate the materials at the nanoscale.
