Low stacking fault energy face centered cubic (FCC) materials contain characteristic defect structures. Stacking fault tetrahedral are one of those rare structures that occur under special experimental conditions. For the first time, stacking fault tetrahedral were observed in Fe-۳۰Mn-۳Al-۳Si twinning induced plasticity (TWIP) steel. Their presence resulted from a quenching heat treatment.
