Abstract
The influence of chromium content on the structure, thermal properties and Curie temperature of (Fe xCr 1 − x 73.5Cu 1Nb 3Si 13.5B 9 (x = 0.85–1.0) alloys in the form of rapidly quenchedribbons is described. The structure of the samples in the amorphous and nanocrystalline state has been studied by transmission electron microscopy (TEM). Chromium alloying results in the refinement of the nanocrystalline grains. From differential thermal analysis (DTA) it is evident that the Cr addition leads to the shift of the first DTA crystallization peak (crystallization of α-FeSi phase embedded in amorphous matrix) to the higher temperatures and to the narrowing of the interval between the first and the second exothermic peak (formation of Fe, Nb borides). Perhaps the formation of Cr borides (thermodynamically more stable than FeNbB) within the temperature range 1180–1260 K is observed on DTA curves. In the case of alloy without Cr the third exothermic peak was not present. Curie temperature decreases with increasing Cr content.
