Abstract: The microstructural and texture evolution of cold rolled low stacking fault energy fcc Fe-30Mn-3Al-3Si alloy was investigated as a function of the cold rolling strain. The alloy was melted and cast in a vacuum induction furnace, hot rolled and annealed before being cold rolled at three different strains: epsilon = 0.035, epsilon = 0.2 and epsilon = 1.2. During the cold rolling process different deformation mechanisms became active depending on the strain. At low strain levels, epsilon = 0.035 and epsilon = 0.2, slip traces were observed whereas at higher strains shear bands appeared. The brass orientation {110}<112> spreading towards the Goss orientation it {101}<001> was dominant at every strain level. The intensity of these texture components increased with increasing rolling strain. The increase of the brass component was more, pronounced when epsilon varied from 0.035 to 0.2, whereas the increase of the Goss component was more pronounced when epsilon varied from 0.2 to 1.2. Additional texture components developed: the epsilon orientation it {111}<110> lying on the gamma-fibre and the S orientation {123}<634> lying on the beta-fibre. This evolution is comparable to other low SFE fcc materials exhibiting the brass-type texture.
