摘要：
This paper deals with the work-hardening behaviour of a Cu-Al//2O//3 alloy rod in the cold-worked and annealed states. The P- TRIAN OP L curve obtained on an electrical tension test device was reported. The work-hardening exponent was measured by using the first work-hardening curve and it was compared with the deformation resistance method. Results show that as the strain rate increases, the work-hardening degree and yield strength become larger, and both properties are affected by the chemical composition.
