A theoretical study on the crystallized fraction and the kinetic parameters by continuous heating techniques. Application to the devitrification of the Sb_0.16As_0.36Se_0.48 alloy

摘要

A procedure has been developed for determining expressions for the fraction crystallized and for the kinetic parameters in non-isothermal reactions in systems involving the formation and growth of nuclei. In this method, the equation for the evolution with time of the volume fraction crystallized ahs been integrated under non-isothermal conditions and assuming an Arrhenian temperature dependence of the nucleation frequency and of the crystal growth rate, thus obtaining a general Expression for the volume fraction ctrsytallized.
