【 摘 要 】

The method of stress relaxation in isothermal aging after deformation is employed to determine recrystallization temperature range (Trec) for 38HN3MFA (35HN3MFA) steel grade. The paper shows that billet final deformation at the temperature lower than Trecfollowed by annealing including heating and aging at Trecenables austenite grain refinement.
