Extension of the Classical Theory of Crystallization to Non-isothermal Regimes: Application to Nanocrystallization Processes
(Elsevier, 2012)
The non-isothermal kinetics of primary crystallization processes is studied from numerically generated curves and their predictions have been tested in several nanocrystallization processes. Single processes and transformations ...

A Finemet-type alloy as a low-cost candidate for high-temperature magnetic refrigeration
(AIP Publishing, 2006)
The refrigerant capacity RC of Fe68.5Mo5Si13.5B9Cu1Nb3 alloy is studied. For the amorphous sample, RC=63 J kg−1 for an optimal reversible cycle with cold and hot ends at 328 K and 520 K, respectively, for a maximum ...

Nanocrystallization Kinetics Under Instantaneous Growth Approximation: Experiments and Cellular Automata Simulations
(Wiley-Blackwell, 2010)
Nanocrystallization kinetics is analyzed in the frame of instantaneous growth approximation, which implies that the time required for a crystallite to reach its final size is negligible with respect to the time required ...

Instantaneous growth approximation describing the nanocrystallization process of amorphous alloys: A cellular automata model
(Elsevier, 2008-07)
A cellular automata simulation based on an instantaneous growth approximation is developed to model the nanocrystallization kinetics. In this frame, the time required for a nucleus to grow up to its maximum size is ...

On the isothermal kinetics analysis of transformations in metastable systems. A combined use of isothermal and non-isothermal calorimetry
(Taylor & Francis, 2007)
A procedure to optimize the isothermal calorimetric data of very slow transformation processes of metastable systems is proposed. The method uses an experimental baseline to identify the transitory effects due to the ...
