Abstract <p>Multicomponent brass alloys are widely used in various industries owing to their exceptional mechanical properties, wear resistance, and corrosion resistance. However, the well-known issue of low crack resistance in binary brasses and their instability during processing limits of their application. The hot deformation temperature of brasses coincides with the dissolution temperature of silicides in the alloy, leading to the formation of unstable regions, loss of coherence between silicides and the matrix, and subsequent spalling under operational loads. Diffusion processes associated with the formation of such structures hinder the further development of phase transformation of the α phase into Widmanstätten or bainitic structures. This work explores the possibility of enhancing the wear resistance and processability of brasses by introducing phosphorus, which promotes stabilization of the α phase and the formation of larger intermetallic compounds. At phosphorus concentrations in the range of 0.15–0.50%, silicon is displaced, resulting in the formation of metastable formations. The results of research provide a foundation for developing new alloys with improved performance characteristics.</p>
