High pressure treatment technique and modification in material properties of aluminium alloys

摘要

High pressure treatment techniques have been one of the most unique tools controlling for thermodynamics of materials. They have been widely used as a synthesis technique of new materials in fields of science and technology. This article shows the overview of a high pressure generation technique and thermodynamic considerations of high pressure phases diagram in alloys. As a example of the application of this technique to alloys, changes of phase diagram in aluminum-rich Al alloys and theirmechanical properties were also shown.
