AbstractAl90Y5Ni1Co4 amorphous and partially crystalline alloys were investigated by means of differential scanning calorimetry, direct current four probe method and X-ray diffraction. The process of crystallization of particles of the order of 10 nm (nanocrystallization) was induced by decreasing the rate of the quenching process from 54 to 39 rev/s or by annealing amorphous samples. The resistivity versus temperature isochronal relation for both groups of alloys was interpreted assuming diffusion controlled growth and zero nucleation rate. The effect of yttrium on the decrease of the growth rate was assumed to be a transformation mechanism leading to nano-size crystalline phase formation.
