Abstract Scope |
Surface enhancement processes like laser peening (LP) are 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 fretting wear behavior comparison between additively manufactured(AM) and wrought(WR) Inconel 625 with LP at elevated temperatures. Deformation mechanisms & grain refinement due to laser peening were first evaluated with advanced characterization techniques like XRD, EBSD, PED, and TEM. To collate these microstructural changes and atomic solute diffusional mechanisms due to elevated temperatures on the nature and origin of wear, detailed spectroscopic studies like EELS and APT were also conducted. |
