“…110 Microstructure characterisation reveals that the intersections of slip bands, grain boundaries and annealing twin boundaries are the favourable sites for the crack nucleation. 92,101 While cracks initiate relatively early during cyclic loading, i.e. within 20% of the fatigue life, the propagation rate is rather slow, which leads to a long fatigue life.…”

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.

“…[15] Studies of the fatigue behavior of TWIP steels showed that the crack propagation took place mainly transgranularly, resulting in ductile striations and protrusions on fracture surfaces. [16] Fatigue cracks tended to nucleate on grain and twin boundaries besides slip bands. [16] The fatigue crack passed along different paths, such as grain boundaries, twin boundaries and slip bands.…”

“…When tested in the as-received state, the dislocation density decreases and the existing twins widen, leading to a cyclic softening due to a lack of dislocation-twin interaction, and a lack of nucleation of new twins. Hamada et al (2009) have studied the high cycle fatigue behavior of Fe-22.3%Mn-0.6C (SFE: 26 mJ/m 2 ), Fe-17.8%Mn-0.6%C with a 200ppm Nb addition (SFE: 23 mJ/m 2 ) and Fe-16.4%Mn-0.29%C-1.54%Al (SFE: 19 mJ/m 2 ) TWIP steels were studied in flexural bending fatigue using a zero mean stress. They report that the three steels had the same 2x10 6 cycles fatigue stress limit of 400MPa, i.e.…”
