The formation mechanism and wear behavior of a gradient nanostructured (GNS) Inconel 625 alloy were investigated using SEM, TEM ball-on-disc sliding tester. results show that surface mechanical grinding treatment (SMGT) induced an approximately 800 μm-deep microstructure, consisting nano-grained, nano-laminated, nano-twined, severely deformed layers, which resulted in reduced micro-hardness fro...

The paper describes the impact of selective laser melting factors including using a nanosecond fibre laser, powers, scanning speed, and thickness layer, on relative density micro hardness Vickers IN 601 samples was studied. Selective (SLM) is commonly used powder bed fusion metal additive manufacturing (AM). Recent advances in have attracted significant industrial interest, especially for produ...
