Overcoming plasticity reduction in a severely deformed nano-grained metastable alloy Open
Most bulk metallic materials reveal an increased strength but a loss of ductility after cold deformation, a phenomenon known as the strength–ductility trade-off. In this study, we propose a strategy to overcome this problem by introducing …
