Russian Metallurgy (Metally) Aims and scope

Abstract

Barothermal treatment of the cast binary alloy Al–8 at % Si has been performed at 560°C/100 MPa/3 h. A microstructure with silicon particles with an average equivalent diameter of ~2.9 microns has been formed in the alloy. Barothermically treated silumin had a yield stress of 67.6 MPa, a tensile strength of 141.6 MPa, and a relative elongation of 34.1%. Cold deformation of the alloy to obtain a foil with a thickness of 16 microns has been realized. A decrease of the aluminum and silicon crystal lattice constants has been established, which is more noticeable at the maximum deformation of the alloy. When deformed, a textured alloy structure is formed with an axis of {100} along the rolling direction. The mechanical properties of the deformed alloy are determined, and the values of yield stress, tensile strength, and elongation equal to ~265 MPa, 305 MPa, and 5.5%, respectively, are obtained for a tape with a thickness of 900 microns. With a higher degree of deformation, for a tape with a thickness of 90 microns, these characteristics have values of ~146 MPa, 165 MPa and 1.4%, respectively, and for the foil with a thickness of 16 microns, ~180 MPa, 196 MPa and 0.3%, respectively.
