Abstract. This article presents a study of changes in the microstructure of Hadfield steel depending on the tensile deformation and cold rolling with the strain/stress level. It has been established that the change in the "σ-ε" curve (at ε = 5%) is accompanied by a 1.5-times decrease in the strain-hardening coefficient.
