Structural relaxation and crystallization processes in Cu55Hf25Ti15Pd5 metallic glassy alloy

We measured the temperature dependence of the apparent specific heat of Cu55Hf25Ti15Pd5 glassy alloy (metallic glass) by a differential scanning calorimetry method during continuous heating, and investigated the structural relaxation and crystallization processes. The results of structural evolution obtained by transmission electron microscopy are discussed in line with the differential scanning calorimetry data. Kinetics of crystallization process of the supercooled liquid above the glass-transition temperature is also studied. This alloy shows a complex relaxation and crystallization processes which are discussed in the paper. (C) 2011 Elsevier Ltd. All rights reserved
