Abstract: The rod-shaped and the tubular amorphous alloys Fe₃₆Co₃₆B₂₀Si₄Nb₄ were respectively prepared by copper mould sucking - casting method; composite materials with nano-crystalline distributed uniformly in the matrix of bulk amorphous alloy was achieved at different temperature and holding time to amorphous alloy Fe₃₆Co₃₆B₂₀Si₄Nb₄ for annealing treatment by the method of amorphous solid crystallisation. Their thermal stability, the characteristics of structure and the distribution situation of nano-crystalline were analysed and checked by X-ray diffraction (XRD), differential scanning calorimetry and transmission electronic microscopy (TEM).

Keywords: amorphous alloys; nanocrystals; nanotechnology; amorphous solid crystallisation; isothermal annealing; copper mould sucking; casting; thermal stability.
