Effect of Pre-Deformation and Baking on High-Speed Deformation Behavior of Steels 2003-01-2765
There has been a big demand for increased vehicle safety and weight reduction. An extensive use of high strength steels is one of the ways to answer the requirement. Increase in strength of steels due to pre-deformation and baking is one of the effective methods to increase the dynamic flow stress, which corresponds to the energy absorption property of steels at high-speed deformations. The effect of pre-deformation and baking on the strain rate dependence of the flow stress was found to be governed mainly by the amount of bake hardenability of steels.
