Abstract Scope Lightweight metals are conventional structural metals having excellent physical and mechanical properties and with good strength-to-weight ratios in the finished products. Nevertheless, there may be an upper limit on the enhancement in mechanical properties when the processing is conducted directly on the alloy. This presentation demonstrates a simple and very rapid synthesis of metal matrix nanocomposites (MMNCs) in several Al hybrid systems which are achieved by processing stacked disks of the two pure metals by high-pressure torsion (HPT) at ambient temperature. These synthesized hybrid systems exhibit exceptionally high specific strength through rapid deformation-induced diffusion and the simultaneous formation of limited different intermetallic compounds. Moreover, enhanced plasticity is demonstrated by the improvement in small-scale mechanical properties through the novel technique of nanoindentation. These new experimental findings suggest a potential for simply and expeditiously fabricating a wide range of MMNCs through HPT.
