Aluminium alloys are widely used in many industrial applications including automobiles and aeroplanes, on account of their light weight. However, the wide-spread use of such alloys was contingent on the discovery of precipitate strengthening as a means for improving the tensile properties of these alloys necessary for most applications. Discovered over a hundred years ago, the technique involves heating alloys to elevated temperatures, which allows nanoscale secondary phases to precipitate in the metal. These precipitates hinder dislocation motion throughout the material and greatly increase their tensile strength. Now, however, Australian researchers led by Christopher Hutchinson at Monash University have developed a room-temperature cycling technique that reproduces and improve...
