The present study mainly focus on the infl uence of Equal Channel Angular Pressing (ECAP) on the mechanical properties, micros tructure, and the texture of a low carbon hi gh Mn TWIP steel. The results showed the HV hardness value, yield strength and ul timate tensile strength of the sample increased whereas ductility decreased with the increased number of ECAP passes. Through ECAP procedure, the average grain size reduced from 199.6 µ m to less than 1 µ m, as well as the twinning fraction. With regard to the texture evolution, the initial samples revealed an anisotropy with the dominant components of Goss and Brass. After ECAP procedure, One pass sample presented the components toward A 1 *and A 2 *, and after four passes, B/ ¿ components were gradually formed which confirmed more stable microstructure
