INVESTIGATION ON CRYSTALLIZATION KINETICS OF Pd-Cu-Si GLASS

摘要

The crystallization kinetics of Pd-Cu-Si glass was studied by means of diferential scanningcalorimetry-Ⅱ.According to Kissinger peak shift meth(?)d and Arrhenius equation,theapparent activation energy was calculated.The crystallization kinetics follows Johnson-Mehl-Avrami equation with n=3.0 within 0.15x0.85.In isothermal treatment,theconcepts of local Avrami exponent and local activation energy have been introduced intoPd-Cu-Si system for understanding the isothermal crystallization process.
