【 摘 要 】

The room temperature strain rate sensitivity of Hadfield steel polycrystals was investigated with the aid of in situ digital image correlation. The current findings indicate that both the rapid work hardening and negative strain rate sensitivity of Hadfield steel polycrystals are influenced by dynamic strain aging.
