Abstract—The effect of the temperature of preliminary annealing (420 or 300°C, 1 h) and the number of roll leveling machine passes (one to three) on the microstructure and mechanical properties of aluminum VD1 (Al–Cu–Mg) thin sheets (3-mm thick) is studied. Alternating bending deformation by one- and two- pass rolling monotonically increases the yield strength of the annealed (at 420°C) alloy from 99 to 133 MPa (by 34.8% relative to its annealed state) without changing the strip geometry and its ductility. Annealing at 300°C increases the yield strength to 300 MPa but reduces ductility. Subsequent alternating bending does not change the mechanical properties of the alloy.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
