Effect of tool geometry on static strength of friction stir spot-welded aluminum alloy
TL;DR: In this paper, a tool-pin geometry significantly affects the hook shape and results in a finer grain structure in the stir zone compared to the cylindrical pin, which is attributed to the finer grain size as well as tensile failure mode as a result of the arrested hook.
