用高压水雾化法制备高硅铝合金粉末．并对粉末的特性进行了分析检测.实验结果表明、用该方法可制得含氧量低、粒度分布均匀、压制性好的合金粉末与同种合金的铸造试样相比，粉末的显微组织得到了显著细化，Si相的形态、尺寸及分布得到了明显改善，其α-Al基体因合金元素固溶度的提高得到了显著强化
High-pressure water atomization method to prepare high-silicon aluminum alloy powder. And the characteristics of the powder were analyzed and tested.Experimental results show that this method can be prepared with low oxygen content, uniform particle size distribution, good compressibility of alloy powder with the same alloy casting sample compared to the microstructure of the powder The microstructure has been significantly refined, the morphology, size and distribution of the Si phase have been significantly improved. The α-Al matrix has been significantly strengthened due to the increase in the solid solubility of the alloying element
