“…The nucleation sites for the fine voids could be at the intersections of twins as observed by in situ and ex situ TEM experiments. 98,99 Besides the mechanism of void formation and growth, the other important parameter affecting the fracture behaviour is the fracture toughness, which has been rarely studied in the literature, 100 which requires further investigation.…”

Manganese rich austenitic twinning induced plasticity steels with high strength and high ductility have been developed in 1990s as promising candidates for automotive applications. Tremendous efforts have therefore been made to explore the unusual deformation and failure mechanisms of these alloys. We provide here a critical assessment of the recent progress in understanding their deformation and failure mechanisms and discuss some scientific challenges that remain unresolved, for example, a physically based twinning kinetics model.

In the present study, the fracture mechanisms of smooth and notched specimens of a high manganese twinning‐induced plasticity (TWIP) steel are investigated quantitatively and compared to that of commercial 304 stainless (304SS) steel and interstitial free (IF) steel. The results show that the dominant fracture mechanism of TWIP steel can either be the formation of void sheets or the propagation of quasi‐cleavage cracks, while the fracture mechanism of 304SS and IF steel are void coalescence. The authors suggest that the special fracture mechanism of TWIP steel is responsible to its limited post elongation, high notch sensitivity, and low fracture toughness.
