a Strain vs. time till rupture. Rupture time: ~530 h. b Strain rate vs. strain till rupture. c Interrupted creep curves at 1 and 5%, strain vs. time. 1% creep time: ~1 h. 5% creep time: ~170 h. d Interrupted creep curves at 1 and 5%, strain rate vs. strain. e Representative STEM ADF overview of 1% creep strain, viewed in [001] zone axis. Region 1: region with low dislocation density; region 2: region with high dislocation density. Blue and red arrows show two types of SFs. f Representative STEM ADF overview of 5% creep strain under (g) condition of \(\left( {1\bar 11} \right)\), showing three different types of SFs, pointed by yellow, orange and green arrows. g ECCI overview of ruptured sample showing dislocations in the γ channel and SFs in the γ′ phase. h Enlarged view from the rectangle in (g). Scale bar is 500 nm.
