Abstract
Influence of carbide forming (Ti and Zr) elements on the interface structure of copper matrix-carbon fibre (Cu-CF) composite was investigated. Specimens composed of Cu-CF embedded in Cu-(0.7 and 3.6 wt.%)Ti and/or Cu-(0.15; 1.3, and 5.1 wt.%)Zr alloys were prepared by hot isostatic pressing. The structure was studied by light and scanning electron microscopy equipped with X-ray analyser, transmission electron microscopy, and selected area electron diffraction. Titanium from the alloy with higher concentration of Ti diffuses onto the carbon fibres located close to (Cu-CF) border with Cu-Ti alloy and reacts with carbon forming titanium carbide. Zirconium diffuses only to border with Cu-CF composite forming Cu-Zr intermetallics and neither effects Cu-CF composite, nor carbon fibre. Copper oxide was found at the interface between carbon fibre and copper matrix.

Key words
