On the short-range order in the Fe84B10C6 amorphous alloy

Abstract Differential scanning calorimetry (DSC), nuclear magnetic resonance (NMR) and Mossbauer effect (ME) experiments have been carried out in order to study the short-range order (SRO) in the Fe 84 B 10 C 6 amorphous alloy. NMR provides clear evidence for the existence of both body-centered tetragonal Fe 3 B-like and orthorhombic Fe 3 B-like SRO in the as-quenched alloy. The NMR results are used as a reference to determine the optimal heat treatment conditions under which the SRO existing in the as-quenched alloy nucleates and grows without undergoing a phase transition. It was found that when the alloy is annealed at the onset temperature for the second stage of the crystallization process, which corresponds to the crystallization initiation point for the SRO in the amorphous alloys, the crystallized precipitates have structures similar to that of the SRO originally existing in the as-quenched alloy.
