Description
Summary:Fe-Cu powder compacts made by pressing and sintering Fe powder and then infiltrating with molten Cu are used because they combine the high thermal conductivity of copper with the strength and abrasion resistance of iron alloys, thereby providing heat sink elements resistant to severe mechanical abuse. Thermal conductivity and thermal diffusivity of these composites are structure dependent since both isolated inclusions and a continuous skeleton of copper occur in the composition range 15-27% Cu. A mathematical model was developed for calculation of the thermal conductivities and diffusivities of these composites (which is presented and discussed in detail in this paper). After mechanical deformation the composite changes, becoming much more an isolated inclusion type structure and less interpenetrating copper skeleton structure.
