在滴管自由落体过程中，用无容器凝固或熔体雾化对20-1000μm的小液滴进行了过冷处理。用电子显微镜、X射线衍射仪和差热分析对凝固后的液滴进行了分析。根据液滴尺寸的不同，已确定了从过饱和Al-SS、金属间化合物Al-6Mn到准晶相的各种相
Small droplets in size of 20-1000 μm of Al-Mn alloys have been undercooled by containerless solidification during free fall in a drop tube or by melt atomization. The as-solidified droplets were analyzed with respect to the phases formed from the undercooled melt by electron microscopy, x-ray diffraction, and differential thermal analysis. Depending on the droplet size, various phases have been identified ranging from supersaturated Al SS , intermetallic Al 6 Mn, to quasicrystalline phases
