文摘
- •
Effect of γ′ precipitate on critical strain and strain localization was studied.
- •
Temperature transition region shifts to low temperature with increasing γ′ content.
- •
Severe localized deformation was accompanied with high-amplitude serration.
- •
High-amplitude serration might be partly induced by stacking faults.
