Grain Refinement in Surficial Cryogenic Grinding

In this article, we adopted surficial cryogenic grinding as a simple method to obtain charming gradient ultra-fine-grained structure. The formation and evolution of ultra-fine-grained microstructure were revealed. The modes of grain refinement were identified in detail, corresponding to different strain rates. Copper sheets (100 × 100 × 3 mm ...
