N2 - The growth behavior of austenite grains and empirical equations to predict the grain size of austenite at different heating temperatures and holding times for AISI O1 steels were presented. From the study, it was found that the grain size of steel depended on the heating temperature and holding time. The roughening temperature was found to be 900 °C. The proposed mathematical prediction showed a good agreement with the experiment results where the value of time index m, activation energy Q, and experimental parameter A for AISI O1 alloy steel were 0.68521, 211,903.27229 J/mol, and 4.25866 × 108, respectively. The average absolute relative error value of the calculation was found to be 7.41% indicating a good accuracy and reliability of our modeling.
