Abstract
Compound preforms are provided having a first region, including a porous ceramic and a second region including a porous or solid ceramic in which the two regions differ in composition. The compound preform is infiltrated with a liquid metal which is then solidified to form a metal matrix composite.
Claims6
A method of forming a metal matrix composite, comprising:
- providing a compound preform, comprising a first region comprising a porous material and a second region comprising a porous or solid material, wherein the two regions differ in composition;
- infiltrating the compound preform with a liquid metal;
- and
- solidifing the metal to form a metal matrix composite.
1 more element
A metal matrix composite comprising:
- a first region and a second region, wherein each of the regions comprises a porous ceramic infiltrated with a metal matrix, the porous ceramic of the first region and the porous ceramic of the second region differing in at least one of composition and volume fraction.
A carrier for an integrated circuit comprising:
- a metal matrix composite comprising a ceramic preform infiltrated with a metal matrix, wherein the composite comprises at least one region having a substantially higher thermal conductivity than the surrounding composite.
