- •
After two cycles of 40% cold tension and annealing, the grain size number changed from 1.5 to 8.5.
- •
The strength, the linear strain hardening rate, and the hardness were enhanced significantly.
- •
Cold expansion followed by annealing is a suitable method for manufacturing fine-grained heavy retaining rings.
- •
Nucleation mechanisms of static recrystallization were given.
