摘要： Magnesium alloy tube members have the potential to reduce weight in automotive vehicle body structures and other applications but they tend to fragment and fail under compressive stress loads applied end-to-end along the longitudinal axis of the tube. It is found that, when the outside surface of the tube is tightly wrapped with fibers (for example, glass fibers or other suitable fibers) and, optionally, resin bonded to the tube surface, the capacity of the magnesium alloy tube to withstand and absorb compressive loads is greatly increased.

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 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： Methods of reducing corrosion between magnesium and another metal are disclosed herein. In one method, a corrosion protection material is cold sprayed at an interface formed between the magnesium and the other metal, the corrosion protection material including magnesium. In another method, a cladding layer is applied to heat affected areas of the magnesium and/or the other metal, at a welded joint, or combinations thereof.

摘要： A magnesium alloy comprising up to about six weight percent zinc and up to about one weight percent cerium may be hot worked to produce an intermediate or final alloy workpiece that exhibits enhanced ductility and strength at room temperature. The addition of zinc and a small amount of cerium may affect the magnesium alloy by increasing strength and ductility, and improving the work hardening behavior.

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.
