Kinetics of crystallization of a ternary titanium based amorphous alloy

Temperature-modulated differential scanning calorimetry (DSC) has been used to study the crystallization kinetics of Ti50Cu20Ni30 metallic glass, The method of Matusita and Sakka for the kinetic study of crystallization seems to be still applicable despite the temperature modulation on four various linear heating rates (5, 10, 15 and 20 degreesC/min) as it utilizes fractio nal crystallization at various temperatures of the crystallization curve in a continuous temperature domain. The modified Kissinger equation, on the o ther hand, underestimates the activation energy of crystallization as it in corporates particular discrete temperature points, i.e. peak crystallizatio n temperatures at different heating rates.
