钢铁研究学报(英文版)

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.
