Abstract
Differential scanning calorimetry was used to study the crystallization processes and kinetics of melt-spun Al{sub 90}Y{sub 10}, Al{sub 90}Fe{sub 5}Y{sub 5} and Al{sub 85}Fe{sub 7.5}Y{sub 7.5} metallic glasses. The characteristics of structural relaxation and glass transition have been observed only in the two ternary alloys. All of the glasses have a relatively high thermal stability. The isothermal experiments show that an applications of the JMA theory is limited to the late crystallization processes, particularly for low concentrated alloys. The crystal nucleation and growth in the early stage devitrification of the glasses will be discussed by means of the local Avrami exponent. (orig.).
