To study the mechanical effect on electrical conductivity of magnetic materials, the electrical conductivity of silicon steel, carbon steel and aluminium alloy with different resistance coefficients at the stage of elasticity deformation and plastic deformation were studied by measuring the resistance. Fitting models were established through theorisation and data measurement and corresponding parameters were given. The following results were obtained. At the stage of elasticity deformation, the electrical conductivity of the material increased rapidly at first and then slowly increased with the increase of stress. At the stage of plastic deformation, the electrical conductivity decreased approximately linearly with the increase of plastic deformation.

Application of nanocrystalline magnetic materials in electromechanical devices is increasingly being adopted, helping to solve energy-saving problems and global warming. Compared with conventional silicon steel materials, nanocrystalline materials show faster flux reversal, lower magnetic loss and more versatile property modification, which result in the successful application in modern electronic devices. Nanocrystalline magnetic materials will be increasingly popularized and used in power electronics, telecommunication equipment and electronic article surveillance systems due to the demands for smaller and efficient devices in the future.

Abstract This paper presents the possibilities of forming the microstructure as well as mechanical properties and electrical conductivity of Cu-3Ti alloy (wt.%) in thermal and thermomechanical processes that are a combination of homogenising treatment, hot and cold working, solution treatment and ageing. Phase composition of the alloy following various stages of processing it into the specified semi-finished product was being determined too. It was demonstrated that the application of cold plastic deformation between solution treatment and ageing could significantly enhance the effect of hardening of the Cu-3Ti alloy without deteriorating its electrical conductivity. It was found that for the investigated alloy the selection of appropriate conditions for homogenising treatment, hot and cold deformation as well as solution treatment and ageing enables to obtain the properties comparable to those of beryllium bronzes.
