摘要： Hybrid articles comprising a molded mixture of a light metal alloy and a polymer are formed by processing (including co-molding and co-extruding) the metal in a semi-solid state at a high shear rate and the polymer in a melt processable state. For example, magnesium alloy particles in a thixotropic condition are mixed with particles or globules of the polymer and molded into a hybrid metal-containing and polymer-containing body. The proportions of magnesium and polymer may be varied substantially depending on the desired properties of the hybrid article. In another embodiment the light metal and polymer may be co-extruded as two or more distinct layers into a solid or hollow hybrid body.

摘要： A method of bonding a metal to a substrate involves forming an oxide layer on a surface of the substrate, and in a molten state, over-casting the metal on the substrate surface. The over-casting drives a reaction at an interface between the over-cast metal and the oxide layer to form another oxide. The other oxide binds the metal to the substrate surface upon solidification of the over-cast metal.

摘要： A segmented tube formed of a magnesium-based alloy and wrapped or jacketed with a reinforcement to apply a restraining force on the external surface of the tube for resisting fragmentation of the tube by the compressive force applied to the end of the tube serves as a structural member for receiving a compressive stress applied to an end of the tube and acting along the axis of the tube toward the opposing end of the tube. The magnesium alloy tube is comparatively light, and the segmented and wrapped or jacketed tube has an increased capacity to absorb compressive forces. The tubes are useful as components of automotive vehicles.

摘要： A method of bonding a metal to a substrate involves forming a plurality of nano-features in a surface of the substrate, where each nano-feature is chosen from a nano-pore and/or a nano-crevice. In a molten state, the metal is over-cast onto the substrate surface, and penetrates the nano-features. Upon cooling, the metal is solidified inside the nano-features, where the solidification of the metal forms a mechanical interlock between the over-cast metal and the substrate.

摘要： A family of die castable, creep-resistant magnesium alloys has been developed for high-temperature structural applications such as automotive engines and transmission cases. These alloys contain between 3% and 6% aluminum, 1.7% and 3.3% calcium, and up to 0.2% strontium. They have demonstrated 25% greater tensile and compressive creep resistance than AE42, a commercial aluminum, rare earth containing magnesium alloy, and corrosion resistance as good as AZ91D. These alloys are estimated to cost less than AZ91D and have good castability in metal molds as used in permanent mold casting and die casting.
