Isoconversional methods of thermal analysis yield activation energies that lack physical meaning for Turnbull-Fisher kinetics: Case study of crystallization of piperine from the melt

Chemical Thermodynamics and Thermal Analysis
Differential scanning calorimetry (DSC) is a useful tool for studying the nucleation rate-limited kinetics of crystallization from the melt. However, applying popular isoconversional methods of thermal analysis to such calorimetric data often yields ...

Non-Isothermal Study of Nanocrystallization Kinetics in Soft Magnetic FINEMET Ribbons

Journal of Advanced Materials in Engineering, 2012
The soft magnetic nanocrystalline Fe73.5Si13.5B9Cu1Nb3 alloy (FINEMET®) is produced by heat treatment of amorphous precursor. Determining kinetic parameters of amorphous structure transformation to nanocrystalline allows the control of microstructure (e ...
