Microstructure and mechanical properties of microalloyed steels after deformation in the two-phase region

摘要

The paper presents the evaluation of influence of the parameters of deformation in the two-phase region on the microstructure evolution and mechanical properties of microalloyed steels. The influence of temperature, strain, and strain rate on the final microstructure was examined. It has been confirmed that the mechanical properties strongly depend on the microstructure of the final product. The effect of microstructure on the mechanical properties can be modified applying varying thermomechanical history. The obtained results can be employed to the design of modern metal working technologies such as the deformation in the two-phase region.
