The melting temperature of tungsten is up to 3410℃, which is the highest one in metals. Furthermore, tungsten has an excellent strength at high temperature. With these characteristics, tungsten is very useful for applications at high temperature. With the development of tungsten and tungsten-based alloys (e.g., W-Cu, W-Ni/Fe), there exit requirements for uniform mcrostructure, superfine grains and good plastics. However, conventional techniques can not meet these requirements.
The nano-related technology can provide a new process for producing ultrafine grain materials. In recent years, ultrafine grain cemented carbides with high performance can be prepared using nanoscale WC powder, and nanoscale WC powder was prepared by reduction carbonization of the nanoscale WO3 powder.
