Description

A friction stir welding takes advantage of elimination of solidification cracking, liquation cracking and porosity associated with fusion-based welding techniques. In the present work, aluminium alloy 2219 in temper T62 (solution treatment and artificially aged), which finds many cryogenic applications, was jointed with friction stir welding techniques. The mechanical properties in terms of tension, fracture toughness and fatigue crack growth, of the AA2219-T62 friction stir welding joints and base material, were studied at both room temperature and cryogenic temperature (20 K). Moreover, the microstructure of the welding joints was investigated by fractographic analysis, and the correlation between the microstructure and the mechanical properties was discussed.
