A tastable, 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.

The invention is directed to the interventionless activation of wellbore devices using dissolving and/or degrading and/or expanding structural materials. Engineered response materials, such as those that dissolve and/or degrade or expand upon exposure to specific environment, can be used to centralize a device in a wellbore.

A method of preparing a mixture of a metal or metal alloy and (Nb.sub.xTi.sub.1-x)C (where 0<x≤1) in which (Nb.sub.xTi.sub.1-x)C in particulate form (either with or without metal powder) is formed into a preform and then if necessary added to the metal. The resulting (Nb.sub.xTi.sub.1-x)C/metal mixture can then be heated to a temperature below the melting point of the (Nb.sub.xTi.sub.1-x)C and optionally dispersed in liquid metal and/or casted and cooled to produce a solid product with improved physical properties.
