Surface enhancement processes like laser peening (LP), and shot peening (SP) are being extensively used in harsh environment applications for decades now to improve the mechanical and surface behavior of parts. With the rapid growth of the metal additive manufacturing industry, it becomes necessary to rigorously study the additively manufactured components trying to achieve comparable or even superior properties with reference to their conventional counterparts. This study showcases a detailed microstructural and surface property comparison between additively manufactured(AM) and wrought(WR) Inconel 625 with LP and SP processes. Surface morphology and mechanical properties, as well as advanced characterization techniques like XRD, EBSD, PED, and TEM, were employed to collate the deformation mechanisms and defect evolution in the microstructure due to the peening processes.
