Abstract

The formation of the icosahedral (i) quasicrystalline phase has been studied in the cast Al 87 Mn 4 Si 2 Be 7 alloy. Under low cooling rates, i-phase particles of about 5 to 15m formed in the a Al matrix. A thorough examination of the microstructure revealed the existence of cubic crystalline phases embedded in the i-particles. Microstructural and thermal analyses indicated that the i-particles nucleated heterogeneously from the cubic AlMn(Si)Be 4 phases by a peritectic reaction, however with a slight misorientation.
