摘要:
Grinding-induced white and dark layers play a critical role in determining the surface integrity of hardened AISI 52100 steel. However, the atomic-scale formation mechanisms remain inadequately characterized. This study systematically investigated carbon redistribution governing the differentiation of superficial and subsurface layers, focusing on the interplay between carbon atom migration and localized structural transformations. Through FIB-TEM characterization, a competitive grain refinement pathway was deciphered within the white layer, an...
