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.
