Abstract:

Effect of thermal deformation regimes on the austenite grain growth is studied in the article. The austenite grain growth curve based on the experimental data is constructed. Conclusion about temperature, deformation degree and rate effect is made.

 

 

Keywords: deformation, recrystallization, dynamic recrystallization, medium-carbon low-alloyed steel.
