This article discusses the changes in the microstructure and properties of brass billets for antifriction rings under intense plastic deformation caused by high-torsion under in a combined matrix. Deformation experiment was performed at room temperature for six cycles. Results revealed that from the initial state, brass showed a threefold increase in strength and microhardness (from 820 MPa to 2115 MPa) after deformation. The greatest increase in strength properties occurred during the first two deformation cycles.
