文摘
- •
The Cu-1Cr-0.1Zr alloy shows a very good thermal stability up to 550 °C after ECAP.
- •
A discontinuous recrystallization was found to occur and PSN mechanism was evidenced.
- •
The annealing texture was found weak and some new components appear.
- •
Hardening is attributed to the Cr clustering followed by the Cu51Zr14 precipitation.
- •
Softening is a result of recrystallization and grain growth progressing.
