The present study is devoted to the effect of cryorolling (– 150 °C) in mill rolls implementing shear alternating severe plastic deformation (SPD) on the microstructure and mechanical properties of the alloy. Comparison of the processes of cryorolling (CR) and rolling at room temperature (RTR) is given. The study of the microstructure of the samples and the mechanical properties showed that CR ensures the production of ultra-fine grained (UFG) material with an average grain size of 350 ÷ 500 nm, as well as an increase in hardness by 162,2 % (118 ± 2 HV) and Rm by 106,34 % (293 ± 5 MPa).
