Abstract: Friction stir welding tool (10) to facilitate stress reduction within the tool that may include a body (20), a pin (30), a tension member (50), and an end assembly (60), the tension member (50) and end assembly (60) facilitating axial compression of the pin (30). The tension member (50) may be decoupled from the pin (30) and/or body (20) of the tool (10) via one or more decoupling members (62). The end assembly (60) may comprise spring members (64) to provide an axial force to the tension member (50). The pin (30) may include various features to facilitate stress reduction proximal the pin (30).

Abstract: A method of producing a metal structure with a grooved wicking surface is provided. An aluminum alloy is provided that is thermomechanically processed to produce grain size and shape suitable for wicking. Then, the alloy is heat treated to produce a continuous etchable phase on the grain boundaries. The alloy is then etched with a solvent that dissolves the continuous etchable phase on the grain boundaries to produce the metal structure with a grooved wicking surface. In addition, the method of producing a laminate metal structure with a grooved wicking surface is provided. The laminate is provided with at least a top layer and a bottom layer where the top layer and bottom layer are made of an aluminum alloy. The laminate is thermomechanically processed to produce grain size and shape spanning the entire depth of the top layer suitable for wicking. Then, the laminate is heat treated to produce a continuous etchable phase on the grain boundaries within the top layer. The laminate is then etched with a solvent that dissolves the continuous etchable phase on the grain boundaries of the top layer to produce the metal structure with a grooved wicking surface where the grooves have a depth equal to the thickness of the top layer where the bottom layer is substantially free of the etchable phase on the grain boundaries.

Abstract: A multi-shouldered friction stir welding tool (10) comprises an integral shank-pin unit (11) having a plurality of pin portions on the shank-pin unit, where the plurality of pin portions for driving into a plurality of joints to perform a friction stir welding operation on the corresponding plurality of joints and, where a shank portion of the shank-pin unit is for attachment to an optional axial tension rod (19), each of the friction stir welding modules comprises a pair of shoulders (13, 14) that is connected to the shank-pin unit where each shoulder has a distal end and a proximal end, where the proximal end of each shoulder faces the pin portion of the shank-pin unit, whereby the shoulder and pin(s) rotate in unison, and a pair of split collars or a pair of nuts that is connected to the shank-pin unit and faces the distal end of each shoulder, where the plurality of friction stir welding modules are connected to each other whereby the modules rotate in unison to simultaneously make a plurality of parallel welds. In addition, a method of friction stir welding a plurality of joints simultaneously comprising using at least one multi-shouldered friction stir welding tool is provided.

Abstract: La presente invención se refiere a un método para producir una estructura de metal con una superficie absorbente ranurada. Se proporciona una aleación de aluminio que es termomecánicamente procesada para producir tamaño y forma de grano adecuado para ser absorbente. Después, la aleación se trata con calor para producir una fase mordentable continua en los límites del grano. La aleación entonces se mordenta con un solvente que disuelve la fase mordentable continua en los límites del grano para producir la estructura de metal con una superficie absorbente ranurada. Además, se proporciona el método para producir una estructura de metal laminado con una superficie absorbente ranurada. Se proporciona el laminado con al menos una capa superior y una capa inferior en donde la capa superior y capa inferior se hacen de una aleación de aluminio. El laminado es termomecánicamente procesado para producir tamaño y forma de grano que abarca la profundidad completa de la capa superior adecuada para ser absorbente. Después, el laminado se trata con calor para producir una fase mordentable continua en los límites del grano dentro de la capa superior. El laminado después se mordenta con un solvente que disuelve la fase mordentable continua en los límites del grano de la capa superior para producir la estructura de metal con una superficie absorbente ranurada en donde las ranuras tienen una profundidad igual al espesor de la capa superior en donde la capa inferior está sustancialmente libre de la fase mordentable en los límites del grano.
