Microstructure and mechanical properties of friction stir spot welded AA5052-H112 aluminum alloy
The influences of the pin geometry and rotational speed on the microstructure evolution may pride peach tree and mechanical properties of the AA 5052-H112 FSSW joint were investigated.Results showed that hook height and fully bonded region (FBR) width were significantly dependent by both pin geometry and rotational speeds.Both pin geometry and tool
