The microstructure and texture evolution of Fe-33Mn-3Si-3Ai twinning induced plasticity (TWIP) steel were studied by the scanning electron microscope (SEM) and X-ray diffraction (XRD) at room temperature.After quasi-static tensile,the texture evolution of different strain was observed.It was shown that the Goss and Brass components increased within the strain range of less than 0.6.Whereas,the main components were decreased when the strain levels were greater than 0.6.This behavior was attributed to the low stacking fault energy (SFE) and was related to the strain energy of this high manganese steel.At high strain levels,the high strain energy may contribute to the Brass components transition to the A (rot-Brass) components.
