Abstract

Formation of crystalline phases is detected at different depths of the surface regions in (Fe1 − xCox)76Mo8Cu1B15 (x = 0, 0.25) alloy by CEMS and CXMS techniques. Magnetite is predominantly present on the wheel sides of the ribbons while the alloy is amorphous. During annealing, formation of bcc-Fe and bcc-Fe,Co starts earlier on the air sides of the x = 0 and x = 0.25, respectively.
