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: Undercooled liquid metallic core-shell particles, whose core is stable against solidification at ambient conditions, i.e. under near ambient temperature and pressure conditions, are used to join or repair metallic non-particulate components. The undercooled-shell particles in the form of nano-size or micro-size particles comprise an undercooled stable liquid metallic core encapsulated inside an outer shell, which can comprise an oxide or other stabilizer shell typically formed in-situ on the undercooled liquid metallic core. The shell is ruptured to release the liquid phase core material to join or repair a component(s).

Abstract: An apparatus for press casting includes a casting mold formed of a fixed mold and a first moving mold operable to move relative to the fixed mold. The apparatus further includes a second moving mold operable to move relative to the first moving mold. A mold cavity, which forms a cast product, is configured by the fixed mold and the second moving mold. When the first moving mold is moved to a first predetermined position, a molten metal passage and a gas exhaust port, which communicate with the mold cavity, are formed at positions outside the mold cavity. A communication between the mold cavity and the molten metal passage, and the gas exhaust port is cut off by the second moving mold when the second moving mold is moved to a second predetermined position while the first moving mold is maintained at the first predetermined position thereof.
