Optimization of Thermal and Deformation Effect during Plastic Deformation and Thermal Treatment of Hot Rolled Heavy Wall Pipes Made of Medium Carbon Martensitic Steel

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 Trec followed by annealing including heating and...

Beschreibung
Zusammenfassung:	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 Trec followed by annealing including heating and aging at Trec enables austenite grain refinement.
