Abstract
Fe-Si-B alloys with small additions of Cu and Nb show a nanostructure after a certain heat treatment. Due to the nanostructure, excellent so ft magnetic properties appear together with nearly vanishing magnetost riction. The most wellknown (standard) alloy is Fe73.5Cu1Nb3Si13.5B9. We focus here on alloys containing 2 and 5 at% Nb and compare results concerning the different crystalline compounds found after certain hea t treatments and also the onset of crystallization with the standard a lloy (3 at% Nb). The variation of the Nb content influences the onset temperatures of nano- and microcrystallization. Also the crystallizati on products vary depending on the content of Nb.
