Theoretical foundations for energy-efficient production of railway rails with improved performance properties

Abstract: Dependence of plastic deformation resistance of chromiumalloyed rail steels on the thermomechanical parameters of deformation (degree, speed, and temperature of deformation) and chemical composition of the steels under consideration was obtained by hot mechanical tests for torsion and compression. According to the obtained data, an increase in rate and a decrease in deformation temperature cause an increase in resistance to plastic deformation. Effect of relative deformation on resistance to plastic de… Show more
