In this work,AlSi10Mg alloy ingots were used.The master alloys were prepared by induction melting a various temperatures ranging from 800 to 1000°C in a corundum crucible.The molten alloy was poured into a tundish and then flowed into the delivery tube.The schematic diagram and the top view of the nozzle are shown in Fig.1.The inner diameters of delivery tubes are 4.0,4.2,4.5,and 5.0 mm,respectively.Different atomization pressures(2.0-4.0 MPa)were used.The N2gas was preheated at 100°C and the delivery tube was also preheated to keep the melt from freezing during the process.All atomization parameters are given in Table 1.
