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).
