摘要： Two aluminium alloy work-pieces are welded together. Firstly, a portion (2) of each work-piece (1) is prepared, the preparation including the performance of a surface treatment, such as friction stir welding, that results in a region (3) extending from the exterior surface into the work-piece having a grain structure that is finer than the grain structure of the work-piece outside that region. Then the work-pieces are welded together by means of a fusion welding process, such as electron beam welding, that joins the respective prepared portions (2) of the two work-pieces (1). The preparation of the work-pieces is so performed that said region (3) extends into the work-piece to a depth that exceeds the depth of material that is caused to melt during the fusion welding process.

摘要： A method for preparing ultra-fine grain titanium or titanium-alloy articles (78) used for adjoining or assembling of detail components is disclosed. Coarse-grained titanium or titanium-alloy materials (52) typically are heated and forced under constant pressure through a friction stir processing tooling device (50) containing a stirring chamber (54) and a stirring rod (58). As the material is passed through the stirring chamber (54), the stirring rod (58) solutionizes the titanium or titanium-alloy material (52) and stirs the material to obtain a homogeneous or uniform material condition. As the processed material exits the stirring chamber (54) of the friction stir process tooling device (50), it reconsolidates as an extremely homogeneous structure possessing ultra-fine grain structure. Titanium or titanium-alloy materials (52) having been processed to achieve such ultra-fine grain material structure may then be manufactured into aerospace structural articles or components such as fasteners (78) that do not require a subsequent heat-treatment steps (Fig. 2).

摘要： The present invention provides an improved structural assembly (10) constructed of a plurality of structural members (11) secured together. At least one of the plurality of structural members defines a first region (11) characterized by comparatively high operational stress and a second region having a locally refined grain structure (16) positioned such that the second region at least partially encompasses the first region to thereby enhance the strength, toughness and fatigue resistance of the at least one structural member in the first region. The present invention also provides a method for selectively improving the strength, toughness and fatigue resistance of a structural member in a region of high operational stress including the steps of casting the structural member in a pre-selected configuration. Regions of the structural member having comparatively high operational stress are identified. The region of the structural member having comparatively high operational stress is then mixed with a rotating friction stir welding probe to locally refine the grain structure of the structural member within the region of high operational stress to thereby improve the strength, toughness and fatigue resistance of the structural member in the region. The improved structural assembly will have an increased operational life, as well as require less stock material with a corresponding decrease in the overall weight of the assembly.

摘要： A method for forming a metal matrix composite (MMC) structure includes forming an assembly including at least two blocks of a primary phase material sharing an interface at which a secondary phase material is disposed. The assembly has a length, a width, and a thickness. The method also includes clamping the assembly to at least one of urge the at least two blocks toward each other or maintain the at least two blocks at a predetermined position. Also, the method includes passing a rotating friction-stir pin along the interface from the front edge to the rear edge. The friction-stir pin has a mixing length extending at least the width of the assembly, and passing the friction-stir pin along the length of the assembly disperses the secondary phase material into the primary phase material and welds the at least two blocks together.

摘要： The method of the invention relates to a method for welding a first (20) and a second (30) layers together. The second melting temperature of the second layer (30), T
m,2 , is lower than the first melting temperature of the first layer (20), T
m,1 . After having formed a layup (50) by placing the first layer (20) on top of the second layer (30), a rotating tool (70) is pressed and translated over at least a friction portion (15) of the upper surface (20u) of the first layer (20) such that the temperature reached by at least a portion of the upper surface (30u) of the second layer (30) is higher than the second melting temperature, T
m,2 . Restraining means allow preventing molten second material from flowing out of the layup (50). Materials of first (20) and second (30) layers are chosen among the following materials: metals, semi-metals, or semiconductors.
