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.

An alloy treatment method is provided, in which a solution containing nickel and/or cobalt is obtained from an alloy containing nickel and/or cobalt and also containing copper and zinc, the method comprising: a leaching step for subjecting the alloy to a leaching treatment with an acid under the condition where a sulfating agent is present to produce a leachate; a reduction step for subjecting the leachate to a reduction treatment using a reducing agent to produce a reduced solution; an oxidation/neutralization step for adding an oxidizing agent and a neutralizing agent to the reduced solution to produce a neutralized solution containing nickel and/or cobalt and also containing zinc; and a solvent extraction step for subjecting the neutralized solution to a solvent extraction procedure using an acidic phosphorus compound-based extractant to produce a solution containing nickel and/or cobalt.

For conditioning build material for fused filament fabrication, thermal power is both added to and removed from a nozzle in a manner that can reduce sensitivity of the nozzle temperature to fluctuations in build material feed rate. The amount of thermal power added is at least as large as the sum of the amount removed, the amount to condition the material, and losses to the environment. The amount removed may be at least as large as half the thermal power required to condition the material to extrusion temperature, and may be comparable to, or much larger than the conditioning amount. The larger the ratio of the amount removed to the conditioning amount, the less sensitive the nozzle temperature will be to fluctuations in build material feed rate. Fine temperature control arises, enabling building with metal-containing multi-phase materials or other materials that have a narrow working temperature range.
