Abstract—The influence of preliminarily annealing conditions (650°C, 45 min; 750°C, 30 min) on the microstructure, texture, and mechanical properties of brass L63 (63% Cu–37% Zn) thin sheets (3 mm thick), which form during alternating elastoplastic deformation in a roller straightening machine, is investigated. Alternating bending is found to increase the strength and to enhance the anisotropy of properties. The preliminarily annealing conditions change the mechanism of structure formation in brass during subsequent alternating bending. Preliminary annealing at a lower temperature results in a higher strength of brass after alternating bending.
