High-strength and low-dwell-sensitivity titanium alloy showing high tolerance to microcracking under dwell fatigue condition

•Bimodal microstructure of Ti-5Al-7.5 V alloy shows a low dwell debit.•Dwell-fatigue loading favors cracking on prismatic planes.•Basal and prismatic slip bands can act as dislocation sources for 〈c + a〉 type dislocations and basal 〈a〉 loops.•Fatigue-like surface crack initiation is consistent with...
