Effect of Cryorolling on Strengthening–Softening Transition in Deformation Twinned Cupronickel Alloy
摘要
The present work focuses on the deformation of a Cupronickel alloy by varying the percentage of rolling passes with low deformation strain at a low speed. The transition from strain hardening to softening was observed with respect to pct reduction ratio. The findings from the 60 pct cryorolled alloy indicate that the strength enhancement, coupled with appreciable elongation, is attributed to the refinement of ultrafine grains, the generation and interaction of dislocations, and the formation of deformation twins.
