Numerical modeling for the effect of pin profiles on thermal and material flow characteristics in friction stir welding
TL;DR: In this article, a numerical method based on computational fluid dynamics is employed to quantitatively analyze the thermo-physical phenomena in friction stir welding with two tools of different pin shapes (axisymmetrical conical tool and asymmetrical triflat tool).

Thermal energy generation and distribution in friction stir welding of aluminum alloys
TL;DR: In this paper, a new method of integrative calculation and measurement is proposed to obtain the more reasonable values of the frictional coefficient and the slip rate, which are both used to characterize the heat generation rate at the tool-workpiece contact interfaces.

Ultrasonic effect on thickness variations of intermetallic compound layers in friction stir welding of aluminium/magnesium alloys
Junjie Zhao,Chuansong Wu,Hao Su +2 more
TL;DR: The formation of intermetallic compounds (IMCs) in friction stir welding of Al and Mg alloys worsens the strength and toughness of dissimilar joints as discussed by the authors, and understanding of the morphology and thickness variation of IMCs at different locations inside the weld will lay solid foundation for mitigating the unfavorable effects of IMC.
