| Özet |
| This study addresses the effects of cryogenic cooling-induced severe plastic deformation (SPD) on microstructure alteration and dynamic recrystallization in the machining of 316LVM alloy. In particular, surface integrity properties such as nanocrystallization, phase transformation, and deformation hardening in the subsurface layer were experimentally investigated. Machining was carried out under liquid nitrogen cooling with cutting parameters consisting of a cutting speed of 300 m/min, a depth of cut of 1.2 mm, and two different feedrates (0.1 and 0.5 mm/rev). An SPD layer with a thickness of approximately 27 to 38 μm and a featureless layer with a thickness of 6 μm were detected in the subsurface of the sample machined at the high feedrate. Furthermore, nanostructures with grain features averaging 93 nm in size were observed in the featureless layer using an atomic force microscope. As a result of X-ray … |
