Abstract
Magnesium AZ91 alloy powder was produced by centrifugal atomization un der various conditions using an inverted disk atomizer. The particle s ize distribution was obtained as a function of the disk shape and rota tion speed. The microstructure of particles and their shape were exami ned and characterized. Their cooling rates were obtained from theoreti cal relations and related to the secondary dendrite arm spacing. (C) 1 997 Canadian Institute of Mining and Metallurgy.
