The Effect of Deformation on the Carbide Precipitation Morphology in the Ti Microalloyed Steel

Article Preview

Abstract:

The influence of deformation on the TiC precipitation morphology in the ferrite matrix has been conducted in the present research. When the isothermal holding temperature maintains at lower temperature, the carbide size and the sheet spacing becomes smaller. Therefore the steel with higher hardness can be gained in the low isothermal holding temperature. Moreover the interface precipitation morphology can usually be seen in the high isothermal holding temperature. It is because the slower α/γ interface moving velocity is benefit for nucleating events to occur in the interface. The carbides nucleated at dislocation can act as the dominant strengthening mechanism in the deformed condition.
