EXO-MELT PROCESS FOR INTERMETALLIC POWDERS

摘要

The methods of powder production for intermetallics are reviewed. An innovative method known as Exo-Melt is described for producing molten aluminides for gas- and water-atomization processes that require a molten metal stream. The Exo-Melt process is based on the effective utilization of the heats of formation of aluminides from their constituent elements. The Exo-Melt process principles are discussed along with a description of a furnace-loading sequence that uses the principles for practical applications. The benefits of the Exo-Melt process are compared with the problems associated with the conventional melting process.
