Abstract

The science and technology underlying the process of melt atomization is introduced, paying particular attention to relevant thermal, solidification and other transport phenomena. Melt atomization has now been developed as one of major produce methods for various metal and alloy powder, and hence it is of both scientific and technological interest. The mechanisms of melt disintegration, the design of typical atomization devices, the influence of key process parameters, the thermal transport in the atomized droplets, and the characteristics of the size distribution are briefly described and discussed.
