Achieving High-Quality Tungsten–Copper Composites Via Deformation-Driven Metallurgy

A novel technique, deformation-driven metallurgy (DDM), was proposed to obtain high-quality tungsten–copper composites based on the principle of severe plastic deformation. A homogeneous distribution of ultrafine tungsten particles improved the continuity of tungsten–copper system. The wear resistance and arc-erosion resistance of DDM composites with superior density and hardness were enhanced by 48.3 and 46.6 pct, respectively. Graphical abstract
