CRYSTALLIZATION KINETICS OF Pd-Cu-Si GLASS

Crystallization kinetics of Pd-Cu-Si glass was studied by DSC. Apparent activation energy was calculated according to Kissinger peak shift method and Arrhenius equation. The isothermal crystallization kinetics, ranged 0.15×0.85, was found to be in agreement with John-Mehl-Avrami equation with n=3.0. Nucleation and growth during isothermal crystallization of Pd-Cu-Si system were approached by introducing the concepts of local Avrami exponent and local activation energy.
