Abstract
Mechanical alloying (MA) of elemental Al and Cr powders of nominal composition Al86Cr14 has been performed by using a conventional ball – mill. The MA process produced a supersaturation of Cr in Al. Isothermal annealing at 590 °C represented in the formation of quasicrystalline phase, in addition of two intermetallic phases Al13C2 and Al14.Cr. A supersaturation solid solution of a α- Fe (AI) and a metastable Al6 Fe phase were formed by MA of a mixture of Al and Fe elements containing of nominal composition Al84 Fe16. However, thermal treatment fail to produce the quasi-phase, various intermetallic phase are obtained. For both alloy systems, milling structure have a nano size of ≈25 nm for Al86Cr14 and ≈37 nm for Al84Fe16, the thermal stability of the produced phases was also examined.
