Effect of strain rate on the microstructures and properties of hot-rolled TWlP steel in the solution condition

摘要：

　　TWIP steel containing 0.21% C,24.4% Mn,0.9% Si,1.84% Al,4.61% Cr,1.89% Ni,0.41% Mo and 0.012% Nb was investigated.Tensile tests of this steel were performed in the strain rate range of 10-4-10-3 S-1.Results indicate that tensile properties of TWIP steel at room temperature are sensitive to strain rate in the studied range.Analyses on the relationship between strain-hardening exponent and strain rates show that the formation of twins during deformation greatly affects the strain-hardening behavior of TWIP steels.
