Microstructural and corrosion study of a “non-comercial” high manganese steel

Abstract. High-Mn steels have great plasticity when subjected to deformation due TWIP or TRIP effects. This work evaluated the microstructural evolution, formation of -Martensite phase taking into account hot rolling 80-60% and solution annealing. Afterwards, microstructures were analyzed by SEM. Volume fraction Austenite phases measured EBSD technique. The steel obtained low energy levels stacking fault, favoring effect TRIP. Corrosion resistance in 0.1M NaCl was open potential circuit potentiodynamic polarization techniques. analysis curves surface after tests showed that with less strain had relatively nobler than more strain.
