N2 - We investigated small fatigue crack propagation in Fe-30Mn-3Si-3Al and Fe-23Mn-0.5C twinning-induced plasticity steels at 30 Hz at ambient temperature by using the replica method with a rotating bending fatigue test machine. The most important difference between the two steels was observed in the non-propagation behavior of small fatigue cracks at the fatigue limits. The Fe-30Mn-3Si-3Al steel did not show fatigue crack non-propagation even at 108 cycles, whereas the Fe-23Mn-0.5C did after 107 cycles, likely because of the occurrence of dynamic strain aging associated with Mn-C coupling.
