| Abstract Scope |
US Army ARDEC has employed inductively-coupled inert gas condensation to synthesize a wide range of nanopowders. This paper focuses on metallic systems; specifically the effects of processing parameters on the particle size, thermal characteristics, and combustion behavior of these materials. A design of experiments was conducted which varied the plasma power, feed rate, system pressure, and quench gas conditions while holding all other parameters constant. The powders were characterized by X-ray diffraction, BET, FE-SEM, TGA/DSC, and bomb calorimetry. The role of each processing parameter on the various properties will be discussed and summarized with effects plots. The consistency of these effects across a number of material systems will be shown. Lastly, the concept of <I>tunability</I> will be discussed. |
