Mechanical Properties of Al-6061 and an Al-6061 Metal Matrix Composite Processed by High-Pressure Torsion

Abstract:

It is now well established that the application of high-pressure torsion (HPT) leads to exceptionally small grain sizes in bulk solids, usually in the nanometer scale. The HPT method thus attracts considerable attention and has been utilized in processing many materials such as pure metals, alloys and even ceramics. This paper describes experiments conducted on samples of an Al-6061 alloy and an Al-6061 metal matrix composite, reinforced with 20 vol.% Al2O3 particulates, in order to evaluate the mechanical properties of the alloy and its composite processed by HPT. The tensile properties of the materials were obtained both at room temperature and at 773 K and representative microstructures were observed using transmission electron microscopy.
