On the Problem of Determining the Layer Thickness in Supermultilayer Materials and the Possibilities of Their Hardening during Cyclic Rolling

The critical thickness of the layers in a laminated composition based on aluminum–copper billets at which the component materials interact across the entire layer thickness due to diffusion is determined. Laminated compositions are fabricated by multicycle rolling. The use of a finite-difference method for solving differential diffusion equations made it possible to determine the solubility zone depth of neighboring components and its dependence on time parameters.
