Galvanically-Active In Situ Formed Particles for Controlled Rate Dissolving Tools
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 he 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.
PREPARATION METHOD OF A LITHIUM-CONTAINING MAGNESIUM/ALUMINUM MATRIX COMPOSITE
The present invention relates to a preparation method of a lithium-containing magnesium/aluminum matrix composite. The preparation method is performed according to the following steps: (1) preparing magnesium ingots or aluminum ingots, preparing lithium metal, and preparing flux and reinforcements; (2) heating the flux to prepare flux melt, and adding the reinforcements to the flux melt to prepare a liquid-solid mixture; (3) pouring the liquid-solid mixture in a normal-temperature crucible, and performing cooling to obtain a precursor; (4) preheating a crucible, adding raw materials, and performing melting to form a raw material melt; (5) controlling a temperature of the raw material melt to 973-993K, adding the lithium metal, performing stirring, adding the precursor, performing stirring and mixing, raising temperature to 993-1013K, and performing standing; and (6) scumming operation should be carried out, and performing temperature casting on composite melt.

Nanocellulosic metal matrix composite
A composite material comprising a metal matrix and nanocellulose supplement. The metal matrix is formed of a metal base material and may be monolithic throughout the composite material. The nanocellulose supplement improves a material property of the metal matrix and is formed of a nanocellulose supplement material dispersed in the metal base material. Importantly, the nanocellulose supplement material does not become damaged when the composite material is formed.
Degradable Metal Matrix Composite
The present invention relates to the composition and production of an engineered degradable metal matrix composite that is useful in constructing temporary systems requiring wear resistance, high hardness, and/or high resistance to deformation in water-bearing applications such as, but not limited to, oil and gas completion operations.

Self-actuating device for centralizing an object
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.
