| Abstract | Mechanical properties of Cu-5 at.%Al alloy with different recrystallization fractions ranging from 0% to 100% are studied by tensile tests at 77 K and 293 K, respectively. The relationship between uniform elongation and recrystallization fraction had been unveiled. The uniform elongation and recrystallization fraction have a transition from single-stage to two-stage relationship with decreasing deformation temperature from 293 K to 77 K, which is related to the strain gradient and deformation twinning in recrystallized grains. In addition, the conventional trade-off relationship between strength and ductility has been broken via tailoring the heterogeneous microstructures at 77 K. |
