Popis: | This paper presents experimental observations of the nanocrystallization process in materials having Fe–Si (FINEMET), a-Fe (NANOPERM), and a 0 -FeCo (HITPERM) nanocrystals coupled through an amorphous phase. Crystallization kinetics and chemical partitioning during crystallization are described. Isothermal nanocrystallization is discussed in the framework of the Johnson–Mehl–Avrami–Kolmogorov model and constant heating rate experiments analyzed in the context of the Kissinger model. 2003 Acta Materialia Inc.
