Streszczenie
The Ni64Cu9Fe8P19 melt spun ribbon was cast using melt spinning. The ribbon in as-cast state was characterised with use of transmission electron microscope (TEM) and X-ray diffraction (XRD). Differential thermal analysis (DTA) of the melt-spun ribbon was made to determine the thermal stability of the alloy. The ribbons in as-cast state and after annealing were characterised with use of Mossbauer spectroscopy and X-ray diffraction to see the change of themicrostructure after heating to elevated temperatures. It has been found that the devitrification sequence consists of progressive formation of (Ni,Fe,Cu)3P phase and (Ni,Fe,Cu)-FCC phase.
