| Abstract |
7091 Al alloy is high strength aluminum alloy and application of this alloy enlarge in current industry system. The powder of rapidly solidified 7091 Al alloy was produced by rapidly solidification processing(RSP). In this study, it was investigated the structures of rapidly solidified 7091 Al alloys ; powder morphology, growth shape, microstructure, particle collisions, satellites, cooling rate. Particle shape was more spherical as decreasing powder diameter, and SDAS was more narrow as decreasing powder diameter, therefore cooling rate was more increased. The effect of powder collision affected on the powder structures and shapes. |
