Abstract: The fractal structures formed in rapidly quenched Al_(86)Mn_(14)alloy have been observed on SEM.Their fractal dimensions are from 1.46 to 1.97.The principal phase examined by TEM and X-ray diffractometer is icosahedral quasicrystalline one with a small amount of Al phase. It is believed that these fractal structures are formed by many aggregated particles during the rapid-quenching process.

Key words: Al-Mn alloy rapid solidification, fractal structure, fractal dimension
