Their fractal dimensions are from 1.46 to 1.97. The principal phase is icosahedral quasicrystalline one, examined by TEM and X-ray diffractometer,in addition to a small amount of Al phase. It is believed that these fractal structures are formed by many aggregate particles during the rapid-quenching process. Key words:  Al-Mn alloy      rapid solidification      fractal structure      fractal dimension      Received:  18 June 1991      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1991/V27/I6/60 1 Shechtman D, Blech I, Gratias D, Cahn J W.
