ABSTRACT:
In the thermal ageing of extruded sections of age-hardenable aluminum alloys the sections are progressed through a system having an initial low temperature zone and a subsequent high temperature zone. In order to secure uniform ageing the sections are progressed in a direction transverse to their length and conveniently are arranged in a single layer and spaced apart to ensure acceptably uniform rate of heating to ageing temperature.
