In the present manuscript, the texture variation of γ austenite, ε martensite and α′ martensite phases are investigated in FeMn (Cr) steels exhibiting both TWIP and TRIP behaviour during uniaxial tensile tests. Samples of three steels with varying Cr content were subjected to tensile tests till fracture on different temperatures ranging from room temperature, at which ε martensite and γ austenite are stable to 453 K, where only γ austenite was present prior to tensile stressing. The developed texture of ε martensite, α′ martensite and γ austenite was examined on multiscale, by TEM orientation mapping, Electron Backscattered Diffraction (EBSD) orientation mapping and X-ray-diffraction pole figure measurements. Correlations between the developed textures and the formation of the martensitic phases are discussed.
