Description
The microstructure and postweld heat treatment of friction stir welds in age hardening aluminium alloys were investigated. Aluminium alloy plate (2014-T6 and 7075-T6 and -T651) of thickness 6.35 mm (0.25 in) was friction stir welded and the joints sectioned transversely. The joint sections were subjected to solution heat treatments, and also to ageing at 120-175 deg.C for various time periods, and characterised by hardness and microstructural studies.
