Abstract
The consolidation and subsequent heat treatment of an inert gas atomized Al-Li-Zr alloy are discussed. The consolidation process used was hot extrusion. The process parameters investigated include extrusion temperature, solution heat treatment and ageing temperature. Attempts are made to correlate the resulting mechanical properties with the extruded structure observed by transmission electron microscopy.
