摘要：
We studied the crystallization processes, the structure and thermal properties of amorphous alloys Cu50Zr50 and Cu(46)Zr(46)A(18) in a wide temperature range. Comparative study of the crystallization kinetics of these amorphous alloys was carried out for the first time using multivariate non-linear regression. It was found that mechanisms of the crystallization of studied metallic glasses are substantially different. The binary alloy is crystallized by branched reaction complex in four steps. For the ternary system was proposed two-step kinetic model of the crystallization process with consecutive reactions. The values of the total energy of activation for each crystallization stage reach to Cu50Zr50: E-1 (345.2 kJ/mol); E-2 (307.9 kJ/mol).
