The studying of high-strengh nitrogen-containing steel structure formation during thermomechanical treatment
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.ΠΡΠΎΠ²Π΅Π΄Π΅Π½ΠΎ ΠΌΠΎΠ΄Π΅Π»ΠΈΡΠΎΠ²Π°Π½ΠΈΠ΅ ΡΠ΅ΠΆΠΈΠΌΠΎΠ² ΡΠ΅ΡΠΌΠΎΠΌΠ΅Ρ
