Abstract

In the present work, molecular dynamics simulation is carried out to investigate the atomic mixing on the Al/Ti interface by severe plastic deformation. The tensile response and fracture mechanisms of the obtained interface are studied. The loading scheme applied in the present work is a simplification of the scenario experimentally realited previously to obtain Al/Cu and Al/Nb composites. It is found that uniaxial compression combined with shear deformation is an effective way to obtain the composite structure. The results indicate that the symmetrical atomic movement took place in the Ti/Al interface during deformation. However, Al atoms diffuse into Ti block easier than Ti atoms diffuse into Al block. Tensile tests showed that fracture took place in the Al part of the final composite sample, which means that the interlayer region where the mixing of Ti and Al atoms observed is stronger than the pure Al part.
