Abstract

This study investigated the effects of surface mechanical attrition treatment (SMAT) on the antioxidation performance of additively manufactured Inconel 718 parts. The results show that SMAT generated a nanograin layer near the part surface with high densities of low-angle grain boundaries, plastic strain and lattice distortion. Oxidation resistance was improved owing to that a continuous oxide scale was quickly formed to protect the underlying materials at the early stage of oxidation by the nanosized microstructure. Moreover, adhesion between the oxide scale and the parent alloy was enhanced because of a high level of compressive residual stress induced by SMAT. © 2025 The Authors
