Optimisation of interface formation by shear inclination: Example of aluminium-copper hybrid produced by ECAP with back-pressure
Source abstract
Abstract
Abstract Hybrid materials present a convenient way of combining properties of more than one material in one product. However, there are problems associated with such manufacturing, particularly, in relation to the properties of the interface between components. Intermetallic compounds can potentially form in this area, whose size and composition can have a profound effect on mechanical properties of the product. In this work, we investigate the effect of temperature, mutual arrangement and hydrostatic pressure on the quality of the interface between Al and Cu parts, processed simultaneously by severe plastic deformation. We show that three intermetallic compounds - θ-Al2Cu, ζ2-Al3Cu4-δ and γ1-Al4Cu9 - form on the interface. It is shown that the formation of these phases on the interface between aluminium and copper highly depends on the combination of diffusion and recrystallization process.
