Abstract

Crystallization of Fe81B13.5Si3.5C2 (Metglas 2605SC) was investigated using angular dispersive X-ray diffractometry and energy dispersive X-ray diffractometry. Transition temperatures were determined by annealing an array of specimens from 0 to 97 h at temperatures ranging from 140 to 490° C. Samples of Metglas 2605SC began to transform in about 2.2 h at 365° C. Crystallization temperatures and products were compared to those previously reported in the literature. In addition, the embrittlement behaviour of the alloy was investigated and the fracture topographies of the as-received and annealed samples were examined and categorized using scanning electron microscopy. The Metglas tended to embrittle easily within short periods of annealing at temperatures as low as 240° C.
