Study of the Strain Resistance During the Tests of the Wheel Steel

Abstract

Increasing attention to the issues of obtaining materials with ultrafine grain structure by plastic deformation methods increases the relevance of studies of the strain resistance σs of metals and alloys during hot deformation.To obtain the required metal structure it is necessary to conduct studies on plastometer of different values of thermomechanical process parameters. In the article, a study of strain resistanceσs of low carbon steel on the plastometer at Czestochowa University of technology was conducted. The adjustment of the strain resistance values with the application of mathematical models was carried out to determine during hot deformation of wheel steel the influence of the temperature θ, rate ξu and degree ϵu of deformation on the strain resistance σs.
