The Variations of Flow Stress and Coercivity of Dual Phase Steel during the Reverse Flow
The variations of flow stress and coercivity of dual phase steel during the reverse flow followed prestrain have been investigated. The results show that the variational curves of coercivity during the reverse flow cam be divided into three domains. The reverse flow curves analysed by using of Hollomon’s equation with computer have two inflexion points. The relation between coercivity variational curves and reverse flow curves and the case of variation of coercivity due to reverse strain have been analysed. The importance of the results in practice, the method for measuring variation of back stress in dual phase steel were discussed and suggested.
