Abstract
Close-coupled atomization systems and methods employing non-axisymmetric gas flow have demonstrated superior efficiency in the production of fine superalloy powder, compared to conventional close-coupled atomization utilizing an axisymmetric annular gas orifice and an axisymmetric melt nozzle. A means has been devised for convening otherwise axisymmetric plenums into non-axisymmetric plenums that produce non-axisymmetric gas flow.
