摘要	The high manganese TRIP/TWIP symbiotic effect steel exhibits excellent combination of strength and elongation due to the transformation-induced plasticity and twinning-induced plasticity. In this paper, by means of a Zwick HTM 5020 high rate tensile test machine; the mechanical behavior of 18Mn-3Al-3Si and 21Mn-3Al-3Si high manganese TRIP/TWIP symbiotic effect steels under dynamic condition, strain hardening rate; true stress and strain hardening exponent show fluctuating with the true stain change, which is caused by the interaction between strain hardening and matrix softening. The microstructure evolution of the specimen was analyzed by OM; SEM, TEM and XRD. The results indicate that the transformation route is gamma ->epsilon, epsilon ->alpha under high-speed deformation; hindering of high-speed deformation to slip, transformation from austenite to martensite, and refinement of austenite matrix due to deformation twins are the main factors of strain hardening; while adiabatic temperature rise effect, epsilon ->gamma reverse transformation and dynamic recrystallization of twins make the matrix softening.
