    Thermomechanical Controlled Processing (TMCP) conditions have been stimulated for nitrogen-containing steel using a plastometer Β«Gleeble 3800Β» at temperatures ranging from 800 to 1100 ΒΊΠ‘. It has been shown that the loss of strength occurs due to dynamic recrystallization (during hot plastic deformation) and static recrystallization (during interstrain interruptions between passes) during TMCP. Recrytstallization behavior conditions have been determined experimentally.ΠŸΡ€ΠΎΠ²Π΅Π΄Π΅Π½ΠΎ ΠΌΠΎΠ΄Π΅Π»ΠΈΡ€ΠΎΠ²Π°Π½ΠΈΠ΅ Ρ€Π΅ΠΆΠΈΠΌΠΎΠ² тСрмомСханичСской ΠΎΠ±Ρ€Π°Π±ΠΎΡ‚ΠΊΠΈ (ВМО) азотсодСрТащСй стали с использованиСм с пластомСтра Β«Gleeble 3800Β» Π² ΠΈΠ½Ρ‚Π΅Ρ€Π²Π°Π»Π΅ Ρ‚Π΅ΠΌΠΏΠ΅Ρ€Π°Ρ‚ΡƒΡ€ 800–1100 ΒΊΠ‘.
