ժҪ Tensile tests of TWIP steels of two compositions are performed in the strain rate range of 10-5-103 s-1. Results indicate that steel 1# does not exhibit TWIP effect but deformation��induced martensitic transformation appears only. There exists TWIP effect in steel 3#. Tensile properties at room temperature are sensitive to strain rate in the studied strain rate ranges. Analysis on the relationship between strain��hardening exponent and strain rates shows that strain��induced martensitic transformation and formation of twins during deformation have significant influence on their strain��hardening behavior.
