Transformation of a High Strength Steel during Deformation at α/γTemperature

Article Preview

Abstract:

The relatively higher alloy content of AHSS leads to complex transformation behavior after finishing rolling and the transformation is unable to complete just after coiling, which causes some extent of deformation due to the transformation dilation. In the present study, low strain rate deformation was performed at γ/α temperature zone after the sample was deformed to simulate the deformation and transformation interaction after coiling by using Gleeble 3800 thermo-mechanical simulator. All the flow stress curves display a sharp decrease after certain strain when deformation temperatures below 750°C. The interaction between deformation and transformation is used to explain the phenomena.
