摘要： A hyper-eutectic aluminum-silicon powder containing extremely fine primary crystal silicon, is prepared by atomizing. First, a molten metal of a hyper-eutectic aluminum-silicon alloy containing phosphorus is prepared. This molten metal or melt is atomized with air or an inert gas and quench-solidified. Aluminum-silicon alloy powder containing primary crystal silicon of not more than 10 .mu.m in crystal grain size is obtained. This aluminum-silicon alloy powder contains at least 12 percent by weight and not more than 50 percent by weight of silicon and at least 0.0005 percent by weight and not more than 0.1 percent by weight of phosphorus. When this hyper-eutectic aluminum-silicon alloy powder is employed, it is possible to prepare a consolidate of powder which has improved mechanical properties, and provides a high yield.
