Abstract

Abstract

The properties of hot rolled ribbed bars with different V contents are investigated. It is found that V can promote gain refinement. Contributions of different strengthening mechanisms to yield strength of bars are computed. The results show that V has a good effect on bar precipitation strength. Through thermodynamic calculations of V element precipitation in HRB400, the influence of V contents on the precipitating temperatures of V(CN) is demonstrated.
