The alloys of W-Cu have been growing industrial interest for superior thermal managing and as microwave materials due to the high thermal conductivity of copper and the low thermal expansion coefficient of tungsten [1].W–Cu alloy parts are generally fabricated by Cu infiltration into W skeleton or liquid phase sintering of W–Cu powder mixtures [2].However,because of the W–Cu system exhibits mutual insolubility,W–Cu powder compacts show very poor sinter ability [3].The Physical-mechanical properties of the composite largely depend on both microstructure and composition relating to fabrication methods and synthesis conditions.
