A combined TWIP/TRIP effect has been observed in a high Mn cold rolled steel. The change in the magnetic property of the material with strain due to the austenite‐to‐martensite transformation has been measured and it shows increasing ferromagnetic behavior with strain. The texture development with strain has been analyzed via the Schmid factor for slip and twin systems in the material. The phase transformation has been related to changes occurring in the {110} <001> and {112} <111> texture components as well as to the profiles of XRD peaks at different strain levels.
