The structural changes and ultimate plasticity of L63 brass which were studied on STD 812 plastometer is described at this work. It was determined that the deformation of samples by torsion and tensile torsion leads to the formation on a L63 brass of a relatively fine-grained structure with grinding of coarse particles especially coarse particles of the β’-phase. It is shown that L63 brass has the maximum value of plasticity in the temperature range of 650 - 850 °C. The results analysis of computer modeling of the billet stress-strain state (SSS) when pressing the bars on a radialshift mill (RSM) of a new construction are presented. Rational modes of deformation of billets on a new RSM are determined in the article, which make it possible to obtain rods and wires with a fine-grained structure.
