摘要： A manufacturing method forms components having a desired shape. A contoured surface is defined for a forming tool for forming a metal blank into the desired shape, wherein respective portions of the metal blank flow over the contoured surface during forming. An intrinsic material flow pattern resulting from the contoured surface is compared to a desired flow in order to identify regions of the contoured surface having an insufficient flow that creates areas in the formed metal blank receiving less than a desired amount of metal. A surface microtexture is applied onto the contoured surface in a pattern selected to increase metal flow along the identified regions by providing a friction in the identified regions that is reduced relative to adjacent regions of the contoured surface.
摘要翻译：制造方法形成具有所需形状的部件。形成轮廓的表面被定义为用于将金属坯料形成为所需形状的成形工具，其中金属坯料的各个部分在成形期间流过轮廓表面。将由轮廓表面产生的本征材料流动图案与期望的流动进行比较，以便识别具有不足的流动的轮廓表面的区域，该区域在所形成的金属坯料中接收小于期望量的金属的区域。以选定的图案将表面微纹理施加到轮廓表面上，以通过在相对于轮廓表面的相邻区域减小的所识别的区域中提供摩擦来增加沿着所识别的区域的金属流动。

摘要： A cutting tool comprising first and second surfaces that intersect at an edge, wherein the first surface (e.g., a rake face, a flank surface or a margin) has a textured region comprising a multiplicity of recesses each having a length greater than its width. The recesses are distributed in a pattern comprising rows of recesses arranged lengthwise along respective lines with spaces between neighboring recesses. The recesses of one row are offset from the recesses of the next row. Each recess of the one row having one end portion that overlaps with an end portion of one recess in the next row and another end portion that overlaps with an end portion of another recess in the next row. The recesses are generally parallel to the edge.

摘要： A method of friction stir welding joints with shims and an associated structural assembly is provided. The structural assembly includes one or more skin members that are disposed and friction stir welded to a substructure. A shim is disposed in a space defined by the other members of the assembly, e.g., between adjacent skin members or between a skin member and the substructure. The shim can be friction stir welded to the other members. That is, the adjacent skin members can be connected via the shim, and/or the skin members can be connected to the substructure via the shim. In some cases, the skin members and the substructure are relatively stiff, and the shim substantially fills the space to reduce flexing of the members during the friction stir welding operation.

摘要： The structural assemblies are selectively reinforced with metal matrix composite in the regions susceptible to mechanical failure. More specifically, a channel is machined in a structural member in an area of relatively high stress. A reinforcing member is inserted into the channel. A metal powder is deposited on and around the reinforcing member. The metal powder is irradiated by a high energy source to thereby encase the reinforcing member in a metal matrix and to consolidate the metal matrix to the interior surface of the channel. The resultant assembly is lightweight and has improved strength and stiffness at room and elevated temperatures.

摘要： A method for weldbonding at least two work-pieces together includes applying an adhesive to a first surface of a first work-piece, and bringing the first surface of the first work-piece into contact with a surface of a second work-piece. The first work-piece and second work-piece are then friction stir or friction stir spot welded together, and the adhesive is cured. The use of bonding tools to maintain the two work-pieces together during curing of the adhesive is eliminated.

摘要： The machined-sandwich structural assembly has two components joined together with a joint of substantially the same strength as the weakest base material. More specifically, the structural assembly includes a first structural member and a second structural member. The first structural member is spaced from the second structural member through a plurality of intermediate members which extend between the first structural member and the second structural member. The plurality of intermediate members are friction stir welded to the first structural member. The resultant assembly requires less stock material, takes less time to machine and has a joint of improved strength.
