Non-isothermal crystallization kinetics of Zr52Cu18Ni14Al10Ti6 metallic glass

Journal of Thermal Analysis and Calorimetry, 2015
In the present work, the thermal analysis of the bulk metallic glass with composition Zr52Cu18Ni14Al10Ti6 has been done by differential scanning calorimetry (DSC) through non-isothermal method. DSC curves indicate a two-step crystallization process at all four heating rates, i.e., 5, 10, 15, and 20 °C min−1.

Evaluation of crystallization kinetics of glasses by non-isothermal analysis

Journal of Materials Science, 2001
Based on Johnson-Mehl-Avrami transition equation, this paper proposes a new non-isothermal method for evaluating the crystallization kinetics of glasses. An equation relating the kinetic parameters of the crystallization activation energy, E, and the frequency factor, v, to the inflection-point temperature, Tf, and the heating rate, β, of differential ...

Kinetics of Non‐isothermal Overall Crystallization in Polymer Melts

Crystal Research and Technology, 1991
AbstractA simple formalism describing the non‐isothermal crystallization kinetics in cooling runs at small undercoolings is suggested. A general mathematical method for analyzing processes of non‐isothermal phase formation, accounting for the proper temperature course of the nucleation rate and of the linear growth velocity is developed.

Non-isothermal crystallization kinetics of Zr41.2Ti13.8Cu12.5Ni10Be22.5 amorphous alloy

Thermochimica Acta, 2014
Abstract The thermodynamics and kinetics of Zr 41.2 Ti 13.8 Cu 12.5 Ni 10 Be 22.5 amorphous alloy under non-isothermal condition were evaluated using differential scanning calorimetry (DSC). The first and third exothermic events at the heating rates of 5 K/min and 10 K/min split into two peaks.

Non-isothermal crystallization kinetics of GeTe4 infrared glass

Journal of Thermal Analysis and Calorimetry, 2015
Non-isothermal crystallization kinetics of the GeTe4 chalcogenide glass was studied in dependence on particle size. Complexity of the obtained DSC data was treated by means of the Fraser–Suzuki deconvolution, and the particular crystallization sub-processes were identified and described in terms of the JMA(2) and AC kinetic models.
