Abstract
Different non-isothermal and isothermal techniques are used to find out the phase transformation kinetic parameters (in this case, activation energy [E] of crystallization, Avrami exponent [n] and frequency factor [k0]) for the crystallization of a newly developed four component Zr58Cu22Al12Ag8 glassy alloy using differential scanning calorimetry (DSC) data. A comparative study is carried out to understand the effectiveness of different methods of evaluation of crystallization kinetic parameters from the DSC traces. n for the alloy varies in the range of 2.5–4 suggesting that growth varies from one to three dimensional with growth mechanism varying from diffusion controlled 3D growth to an interface controlled 1D growth.
