Rotating atomization processes of reactive and refractory alloys

Abstract

In the last 20 years, powder metallurgy (PM) has made remarkable progress. The PM route is now recognized as a competitive, and some times, alternative, way to conventional metal forming. Research in this area has shown the capability of the high performance technology in the powder production of new and unusual materials. Some of these important powder production methods are known as rotational atomization processes which have demonstrated their suitability for new PM products such as reactive and refractory compositions of great interest for aerospace, nuclear, electronic and metallurgical applications. This article outlines some of the most important advanced techniques of metal powders production in the field of rotary atomization.
