A ceramic reinforced metal composite (CRMC) comprising a composition composite as an interpenetrating network of at least two interconnected composites is described. The interpenetrating networks comprise a ceramic matrix composite (CMC) and a metal matrix composite (MMC). The composition composite is particularly useful as an electrically conductive pathway extending through the ceramic body of a hermetically sealed component, for example, a feedthrough in an active implantable medical device (AIMD).

A nanocomposite metal material includes a carrier formed of Zr and two-element metal particles supported on the carrier. The two-element metal is formed of Cu and Ni, and a degree of oxidation of the carrier is more than 31% and 100% or less. In a case where the nanocomposite metal material is disposed in a reaction furnace of a thermal reactor, the inside of the reaction furnace is brought into a vacuum state, and the inside of the reaction furnace is heated to a temperature range of 250° C. or higher and 350° C. or lower with a heating mechanism included in the thermal reactor while supplying at least one of hydrogen gas and deuterium gas into the reaction furnace, excessive heat of the nanocomposite metal material is 100 W/kg or more.

A caster assembly configured to process and store a material includes a reaction chamber, a storage assembly configured to store material processed in the reaction chamber, and a blower configured to process and store the material. The reaction chamber includes a vessel configured to hold the material in a melted state prior to processing and a powder generating assembly configured to receive the material from the melting vessel. The powder generating assembly includes a feeding chamber and a feeding device disposed at least partially within the feeding chamber. The feeding device includes at least one nozzle configured to inject inert fluid, where the fluid is a gas, liquid, or combination of the two into the feeding chamber and a material inlet through which the material is configured to flow into the feeding chamber to be exposed to the inert fluid, where the fluid is a gas, liquid, or combination of the two.

A preparation method for a W—Cu composite plate with a Cu phase in finger-shaped gradient distribution is provided. The method includes adding WO.sub.X powder obtained with ammonium metatungstate as a raw material into W powder through a combustion synthesis method, adding a binder and a pore-forming agent to prepare a slurry, then performing tape casting, soaking in water and sintering to obtain a W framework with pores in finger-shaped distribution, and then infiltrating Cu to obtain a target product. The Cu phase in the W—Cu composite material prepared by the present method is distributed in a finger-shaped gradient manner from an infiltration surface to the interior of a specimen, the Cu phase and the W phase are mutually pinned, and the W—Cu interface has good bonding strength. The present method has the characteristics of adjustable material component performance, simple process, low cost, suitability for large-scale production and the like.
