Development of Non-reactive F-Free Mold Fluxes for High Aluminum Steels: Non-isothermal Crystallization Kinetics for Devitrification

Metallurgical and Materials Transactions B, 2020
It is necessary to study crystallization from glass (devitrification) for non-reactive F-free CaO-Al 2 O 3 based mold fluxes; this is especially important for the development of mold fluxes for continuous casting of high aluminum steels. To the knowledge

Non-isothermal crystallization kinetics of an intermetallic CoSn phase

Journal of Physics Communications, 2020
Abstract Herein, the crystallization kinetics of the intermetallic CoSn phase, nucleated and grown in the microstructure of a binary CoSn alloy, have been reported. Differential scanning calorimetry traces under non-isothermal conditions were obtained and used to extract the activation energy (

Fast algorithm for computing non-isothermal crystallization kinetics [PDF]

Journal of Non-Crystalline Solids, 2016
Abstract A fast algorithm is presented for computing fractional crystallized volume of an amorphous solid under non-isothermal conditions, as a function of the number of discrete time intervals, temperature history and (temperature dependent) nucleation and growth rates.
