Resumen:
Perturbed Angular Correlation study on melt-spun Cu60Hf20Ti20 and Cu60Hf40 is presented. The influence of Ti addition on thermal stability and crystallization mechanism is followed by differential scanning calorimetry. The evolution of quadrupole parameters with measurement temperature is analyzed in both alloys in order to get insight into the crystallization process. Although an intricate crystallization mechanism is observed for the Ti content alloy, the final stage is similar, irrespective of minority atom.
