FIB-assisted TEM study of an oxide array in the root of a friction stir welded aluminium alloy

A local region in the preferentially etched line at the root part of a friction stir welded Al alloy was directly observed by TEM. TEM clarified that the preferentially etched line consisted of zigzag region having a high density of amorphous Al 2O 3 particles which originated from the initial butt...

Description
Summary:A local region in the preferentially etched line at the root part of a friction stir welded Al alloy was directly observed by TEM. TEM clarified that the preferentially etched line consisted of zigzag region having a high density of amorphous Al 2O 3 particles which originated from the initial butt surface oxide layer.
