摘要：

Tensile tests of TWIP steels of two compositions are performed in the strain rate range of 10(-5) - 10(3) 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.
