Important Tungsten alloys include W-Ni-Fe, W-Ni-Cu, W-Cu, and WC-Co. In the 21th century, nanograin tungsten alloys will emerge as new materials with muctiple-functions and ultrahigh properties. Nanograin bulk tungsten alloys prepared from nanocrystalline powders will exhibit superior physical and mechanical properties, and have potential advantages in microelectronic applications, such as, heat sinks, electronic packages, and anti-armor applications. This paper reviews the current research on nanograin refractory tungsten alloy composite powders, introduces numerous technique for nanometer tungsten alloy powder preparation, and points out research directions of nanometer refractory tungsten alloy materials.
