Research on Dynamic Recrystallization and Microstructures of Microalloyed Steels
The true stress and strain curves at different finishing temperatures are measured by gleeble-150 0 .The effects of finishing temperatures and quantities of microalloyed elements on dynamic recrystallization are researched primarily. The researched results indicate that dynamic recrystallization of deforming austenite being rolled can be prohibited significiantly by adding V and Ni. Therefore,trival and uniform microstructures can be obtained though finishing temperature is higher.
