Abstract: A castable, moldable, or extrudable magnesium-based alloy that includes one or more insoluble additives. The insoluble additives can be used to enhance the mechanical properties of the structure, such as ductility and/or tensile strength. The final structure can be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final structure as compared to the non-enhanced structure. The magnesium-based composite has improved thermal and mechanical properties by the modification of grain boundary properties through the addition of insoluble nanoparticles to the magnesium alloys. The magnesium-based composite can have a thermal conductivity that is greater than 180 W/m-K, and/or ductility exceeding 15-20% elongation to failure.

Abstract: A remanufacturing method for a metal part having a damage. The damage groove is divided into a number of levels, and the groove bottom is treated by absorption layer-free laser shock peening to remove surface impurities and to refine surface-layer crystal grains. Then a cladding layer is formed by laser cladding. The process is repeated until the groove is completely filled by the cladding layer to higher than the surface of the metal part and the cladding layer higher than the surface is cut by a mechanical processing and polished, and the upper surface of the laser cladding layer is subjected to large-area overlapped laser shock peening.

Abstract: An earth-boring tool includes a tool body, at least one cutting element, and a retaining member comprising a shape memory material (e.g., alloy, polymer, etc.) located between a surface of the tool body and a surface of the cutting element. The shape memory material is configured to transform, responsive to application of a stimulus, from a first solid phase to a second solid phase. The retaining member comprises the shape memory material in the second solid phase, and at least partially retains the at least one cutting element adjacent the tool body. The shape memory material may be trained in a first phase to a first shape, and trained in a second phase to a second shape. The retaining member may be at least partially within a cavity in the first phase, then transformed to the second phase to apply a force securing the cutting element to the tool body.
