Abstract

Highlights: [•] Compared with T7451 treated sample, RRA treated one exhibits enhanced fatigue crack growth resistance. [•] EBSD analysis showed crack growth behaviors within grains or grain boundary in both samples. [•] Examination of micro fractures and surfaces were performed with SEM in both samples.
