Abstract

Discrete powder particles of copper 14 and INVAR 12 are mixed together in a container 16 and packed into a powder metal article. This article is hot vacuum degassed and vacuum sealed and then heated to temperature well below the sintering temperature of copper or INVAR. Immediately after heating the article, it is subjected to a high pressure, high strain force such as extrusion through a die thereby yielding a fully dense, strong composite material 10 with excellent combined thermal expansion and conductivity properties.
