The structure and mechanical properties determined by microhardness measurements of nanocrystalline Al86Y5Ni5TM4 (x = 4 at. %) alloys, where TM = Cu, Fe, were examined. The effect of replacement of Ni by TM elements on structure of the alloys obtained by rapid solidification and by isothermal annealing of initially fully amorphous alloys was investigated. This replacement extended the temperature region in which the A1 phase precipitates. The control of cooling rate and changes of annealing temperature caused the formation of nanoscale fcc-Al particles embedded in an amorphous matrix. The volume fraction of the nanophase particles and average size of Al-phase were calculated. The hardening effect induced by nanocrystallization was observed.
