Abstract
The process of crystallization of particles with dimensions of the order of 10 nm in amorphous Fe 75.5Cu 1Nb 3Si 12.5B 8 (nanocrystallization) is investigated by three experimental techniques: isothermal resistance measurements, X-ray diffraction, and electron microscopy image analysis. The results show that the crystallization rate decreases slightly with increasing fraction of crystalline material. This decrease is mainly caused by the small growth rate of the larger crystals. Possibly rate-limiting Nb-diffusion and an enrichment in Nb of the amorphous phase are the decisive processes.
