Abstract
The work presents experimental data on influence of temperature, degree and speed of deformation on resistance of deformation of the carbonaceous low-alloyed steel. The research was conducted at test of samples on the torsion STD 812 plastometer of Chenstokhovsky University of Technology. According to the study of deformation resistance, hardening curves were constructed for carbon low-alloyed steel at different speeds and temperatures of deformation. Common to all curves is a high hardening speed of the hardening in the initial period of deformation when the action of relaxation processes is not apparent. The authors have installed important for the practical use quantitative characteristics of the influence of the temperature-rate conditions of deformation on the maximum value of the deformation resistance reduction as a result of relaxation processes and on the average speed of hardening at the interval 0<εu<εu*.
