摘要： Magnesium alloys and a process of manufacturing an article using magnesium alloys. During additive manufacturing, where the magnesium alloy is being deposited in a layer-by-layer manner, solidification of the melted portion of a deposited layer is performed in such a way as to ensure that about 15 percent or more of the portion being solidified includes a non-equilibrium eutectic constituent. This in turn reduces the likelihood of encountering solidification conditions that otherwise would lead to hot tearing problems. Further, upon subsequent heat treatment of the solidified layer, the eutectic constituents that were used for hot tearing resistance are dissolved so that the solidified layer may be returned to a substantially single-phase magnesium matrix such that desirable material properties such as improved flammability point, improved corrosion resistance and one or more of high yield strength, ultimate tensile strength and elongation are promoted.

摘要： The present disclosure discloses a Mg—Gd—Y—Zn—Zr alloy with high strength and toughness, corrosion resistance and anti-flammability and a process for preparation thereof. Components and mass percentages in the Mg—Gd—Y—Zn—Zr alloy are: 3.0%≤Gd≤9.0%, 1.0%≤Y≤6.0%, 0.5%≤Zn≤3.0%, 0.2%≤Zr≤1.5%, the balance being Mg and inevitable impurities. The process for preparation thereof comprises: adding pure Mg into a smelting furnace for heating, then introducing mixed gases of CO2 and SF6 into the furnace for protection; adding other raw materials in sequence when the pure Mg is completely melted; preparing an ingot; conducting a homogenization treatment on the ingot prior to extrusion; conducting an aging treatment on the extruded alloy. The present invention obtains a wrought magnesium alloy having both superior overall performances and good fracture toughness, corrosion resistance and anti-flammability, with a small amount of rare earth element by adjusting the proportion of the alloy elements and by conventional casting, extrusion and heat treatment processes.

摘要： 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.
