Abstract:

Crystallization of M₇₈Si₉ (M=Fe,Co,Ni) glasses has been studied by differential scanning calonmetry (DSC), thermomagnetic gravimetry (TMG) and X-ray diffraction. Devitrification for Fe and Co alloys occurs in two main stages: a primary precipitation of metal-rich (Fe,Si or Co, Si) phase and a polymorphic reaction to give a Fe₂B- or Co₂B-type phase. For Ni alloy a single crystallization stage was detected by DSC, and Ni and Ni₃B-type phases were found in crystallized samples.
