Effect of annealing on the microstructure and mechanical properties of 1060Al/T2Cu composite plates after cold rolling

This study investigates how annealing at 150°C and 400°C influences the interface evolution, microstructural changes, and mechanical properties of cold-rolled 1060Al/T2Cu composite plates, revealing that low-temperature annealing enhances both strength and ductility through recovery, while high-temperature annealing promotes interfacial diffusion and recrystallization to significantly improve ductility at the expense of strength.
