Novel Method to Count Prior-Austenite Grain Size and Modeling of Initial Grain Size in DP590 Steel

  A novel method was proposed to count prior-austenite grain size.Information such as grain diameter,grain area and grain size distribution can be drawn conveniently by using the software of Photoshop and Image-Pro Plus..In order to quantify the initial grain size in Beck equation,the effects of heating rate and soaking temperature on austenite grain size of DP590 were investigated.A model for initial grain size as a function of temperature and heating rate was developed.The good agreement between the predicted value and experimental data shows the reliability of the proposed model.
