The role of molybdenum on evolution of deformation texture in the cold rolled Fe30Mn5Al1C-xMo lightweight austenitic steels

The effect of molybdenum addition on the evolution of deformation texture during cold rolling is studied in Fe30Mn5Al1C-xMo (x = 0-3 wt%) light weight austenitic steels using EBSD. All the alloys have random texture prior to cold-rolling. After cold rolling, molybdenum promoted the formation of Brass-type texture. This texture can be attributed to dislocation based active deformation mechanisms because no deformation twins were found in the microstructure. The intensity of the major texture components: Brass and S increased up to 2 wt% Mo and then decreased. The increase in the molybdenum content did not affect mechanical properties significantly.
