Materials with high performance regarding thermal properties as well as mechanical properties are required for application in high heat-flux environments, especially in new technologies for advanced energy production such as plasma facing materials in fusion reactors. With the incorporation of high strength and ductile W wire in a W matrix, new tungsten composites can show significantly increased mechanical properties and develop so-called pseudo-ductile behaviour. This new technology could also find promising applications in areas such as high temperature x-ray cathodes, concentrated solar power or casting molds.
