| Abstract: | Based on the transformation kinetics and thermodynamics an algorithm for predicting ferrite grain size after continuously cooling transformation from deformed austenite to ferrite was suggested. Calculated results of computer simulation wtih the algorithm are in so good agreement with the measured ones in the pilot experiments, that the theoretical algorithm is feasible. |
