N2 - This paper presents the results of computer simulation by the cellular automata method of preliminary heat treatment and radial-shear rolling of M1 copper alloy. Quenching and annealing processes were modeled as pre-heat treatment modes. The radial-shear rolling stage consisted of three passes with a compression of 3 mm per pass. The variable parameters were the roll rotation speed (40 rpm, 70 rpm and 100 rpm) and the workpiece heating temperature before rolling (20°C and 200°C). It was found that the most effective mode of pre-heat treatment for M1 copper alloy is quenching at 700°C. The most rational value of the workpiece heating temperature before rolling is 20°C, since in this case, at all selected speeds, the recrystallization process does not start, which contributes to intensive grinding of grain in the surface layers and on the periphery. An increase in the roll rotation speed causes additional deformation heating, which contributes to the recrystallization and suppression of intensive grain grinding. Therefore, when heating the M1 copper alloy to 200°C, it is not recommended to increase the rolling speed above the nominal. © 2023, University of Chemical Technology and Metallurgy.
