Abstract
The crystallization kinetics of Cu–Ti glass at three different compositions has been studied by differential scanning calorimetry (DSC). The DSC traces have been analyzed in terms of activation energy, stability and dimensionality of growth by four different models viz. the Kissinger equation, the Ozawa equation, the Matusita equation and the Gao and Wang equation. The activation energy increases with Cu content and the highest crystallization temperature occurs for the composition Cu 50Ti 50 indicating locally increased chemical short-range order at this particular composition. The average value of the Avrami exponent comes out to be 4 which shows that the crystallization process takes place via three-dimensional parabolic growth with bulk crystallization.
