Log-Normal Melt Pulsation in Close-Coupled Gas Atomization [PDF]

Metallurgical and Materials Transactions B, 2013
High speed photography coupled with sophisticated image analysis has been used to study low-frequency pulsation during close-coupled gas atomization. At high gas pressure the instantaneous melt delivery is described by two superimposed log-normal distributions, one with a high standard deviation but little melt at the atomizer tip, the second with low ...
