AbstractThe present work investigates delayed fracture (DF) behavior of a twinning-induced plasticity (TWIP) steel in a neutral environment using deep-drawn cup specimens. The specimens are exposed to different corrosive environment to observe the occurrence of DF. The results reveal that the DF of TWIP steel is caused by a hydrogen-assisted transgranular stress corrosion cracking mechanism. Besides the residual stress, we demonstrate that the plastic strain plays a crucial role on the DF of TWIP steel by accelerating the crack growth rate.
