摘要： A castable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contains an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.

摘要： A method of optimising one or more physical properties of an alloy comprises conducting a plurality of trials per an experimental design on a plurality of candidate alloys. Each trial comprises measuring a plurality of values of each physical property of the candidate alloys for different values of a plurality of parameters, wherein the parameters comprise respective concentrations of the two or more constituents, and one or more process parameters. The method further comprises fitting the plurality of values of the physical property and the plurality of parameters to a response surface model; and determining, from the fitted response surface model, optimised values of the parameters that optimise the respective responses; wherein the response surface model describes a non-linear relationship between a time integral of each of the physical property and a linear combination of non-linear functions of the plurality of parameters.

摘要： A method of forming high quality metallurgical bonds in a composite casting is provided. The bonding technology includes the step of introducing a liquid material to contact the solid components placed in a mold cavity, applying an external field to generate stifling near the solid/liquid interface to wash off bubbles and oxide particles that prevent the liquid material from reacting to the solid component, and causing progressive solidification from the surfaces of the solid component to the liquid to drive away bubbles in the mushy zone near the bonding region. High quality metallurgical bonds are formed within the composite casting after the liquid solidifies. The resultant large composite casting has minimal defects, such as pores and oxides, at the interfaces between the solidified material and the solid objects.
