Fabrication of hybrid metal systems through the application of high-pressure torsion

Fabrication of hybrid metal systems through the application of high-pressure torsion
Fabrication of hybrid metal systems through the application of high-pressure torsion
This presentation demonstrates a simple and very rapid synthesis of metal matrix nanocomposites (MMNCs) in Al-based hybrid systems which are achieved by processing stacked disks of two pure metals through the application of high-pressure torsion (HPT) at ambient temperature. These synthesized hybrid systems exhibit exceptionally high hardness through rapid deformation-induced diffusion and the simultaneous formation of different intermetallic compounds. The experiments also show further improvement in mechanical properties is available by increasing the numbers of HPT turns and additional short-term annealing. Thus, by demonstrating the fabrication of the Al-Mg and Al-Cu hybrid systems, the present paper suggests a potential for simply and expeditiously fabricating a wide range of MMNCs through HPT.

Abstract

This presentation demonstrates a simple and very rapid synthesis of metal matrix nanocomposites (MMNCs) in Al-based hybrid systems which are achieved by processing stacked disks of two pure metals through the application of high-pressure torsion (HPT) at ambient temperature. These synthesized hybrid systems exhibit exceptionally high hardness through rapid deformation-induced diffusion and the simultaneous formation of different intermetallic compounds. The experiments also show further improvement in mechanical properties is available by increasing the numbers of HPT turns and additional short-term annealing. Thus, by demonstrating the fabrication of the Al-Mg and Al-Cu hybrid systems, the present paper suggests a potential for simply and expeditiously fabricating a wide range of MMNCs through HPT.
