Abstract
Tungsten-Copper composites are materials that offer an interesting combination of thermophysical and mechanical properties: a coherent copper matrix - ensuring a high conductivity as well as an acceptable ductility- can be combined with the inherent hardness and low thermal expansion of tungsten in order to obtain a material with tailored thermal management and mechanical properties. Furthermore, these composites can easily be fabricated by liquid copper infiltration. For these reasons, tungsten-copper composites are of direct interest as heat sink materials used in highly loaded components of future nuclear fusion reactors where tungsten plasma facing components have to be joined to a high thermal conductivity material, such as copper. The aim of this study is the presentation of the microstructural and mechanical properties of novel tungsten-copper composites as a function of temperature. For this purpose, hardness and elastic modulus have been measured using instrumented and Vickers indentation and as well as resonance frequency analysis, respectively. Flexural strength and fracture toughness of the materials have been determined by means of 3-point bending tests on smooth and laser notched samples in the temperature range between room temperature and 800 °C under high vacuum atmosphere. Finally, a series of tensile tests have been conducted in the same temperature range and atmosphere.
