Abstract
A thermal investigation concerning the behaviour of amorphous alloys of 51% Cu, 10% Ni and 39wt % Ti (denoted by A) and of 13% Cu, 27% Ni and 60 wt % Ti (denoted by B) was performed using the differential scanning calorimetric method, alternatively in hydrogen and nitrogen atmosphere. It was shown that the crystallization (devitrification) is carried through in two and three different steps for alloy A and alloy B, respectively, within the temperature interval 573 to 823 K (300-550° C). Activation energies of each individual crystallization step, as well as frequency factors, rate constants, half-times and enthalpies of the crystallization reactions were determined.
