Thermally induced crystallization of Fe73.5Cu1Nb3Si15.5B7 amorphous alloy

Popis výsledku v původním jazyce

Thermally induced crystallization of Fe73.5Cu1Nb3Si15.5B7 amorphous alloy occurs in two well-separated stages: the first, around 475 degrees C, corresponds to formation of alpha-Fe(Si)/Fe3Si and Fe2B phases from the amorphous matrix, while the second, around 625 degrees C, corresponds to formation of Fe16Nb6Si7 and Fe2Si phases out of the already formed alpha-Fe(Si)/Fe3Si phase. Mossbauer spectroscopy suggests that the initial crystallization occurs through formation of several intermediate phases leading to the formation of stable alpha-Fe(Si)/Fe3Si and Fe2B phases, as well as formation of smaller amounts of Fe16Nb6Si7 phase. X-ray diffraction (XRD) and electron microscopy suggest that the presence of Cu and Nb, as well as relatively high Si content in the as-prepared alloy causes inhibition of crystal growth at annealing temperatures below 625 degrees C, meaning that coalescence of smaller crystalline grains is the principal mechanism of crystal growth at higher annealing temperature
