Abstract:A novel solid atomization technology, which using high velocity gas jet-stream rich in solid salt particles as atomization medium, was developed. The results show that using this novel atomization process can produce various metal and alloy powders with finer particle size, finer microstructures and higher cooling rat e than those powders produced by the conventional gas atomization technology.

 

Key words: powder processing; rapid solidification; powder metallurgy
