Fig. 1.. The goal of this work was to increase the heat transfer coefficient and thus the cooling rate by developing novel cooling strategies during molten metal gas atomization. Gas atomization (GA) with conventional cooling, spray cone cooling (GA + SCC), and liquid quenching (GA + LQ) were used in this study. Both cooling techniques used distilled water as a cooling medium. Spray cone cooling used distilled water to cool the spray cone from all angles, whereas liquid quenching was performed to quench the molten droplets.
