Abstract

Amorphous ribbons of Al_92−xCo₈Dy(Ho)_x (x = 6 and 10 at.%) composition were produced by a standard planar flow casting method. Their kinetics of crystallization was studied by X-rays, DSC and electric resistivity. The phase composition was determined at each stage of crystallization. In order to increase the stability of amorphous state, use of alloy with high REM content and holmium is preferred to dysprosium.
