Figure 8 shows the correlations of the predicted values that were calculated from two models with the experimental values. The calculated values of R and AARE from the simplifified model were 0.9895 and 6.937%, whereas the values from the modifified model were 0.9923 and 6.063%, respectively. These results indicated that the modifified Sellars model give an accurate predictive capability to evaluate the grain size of TC4–DT alloy.
