Abstract

The focused ion beam assisted transmission electron spectroscopy study of an oxide array in the roof of a friction stir welded aluminum alloy was presented. The preferentially etched line consisted of a microstructure containing a high density of fine Al₂O₃ particles with an amorphous structure. It was found that the microstructure was formed by fragmentation and dispersion of Al₂O₃ oxide layer from the initial but surface during stirring in friction stir welding (FSW).
