Mechanical amorphization of the Fe/sub 73.5/Cu/sub 1/Nb/sub 3/Si/sub 13.5/B/sub 9/ alloy

In our work a reversible process for creating nanocrystalline Fe/sub 73.5/Cu/sub 1/Nb/sub 3/Si/sub 13.5/B/sub 9/ by annealing the amorphous ribbons was observed. The original amorphous ribbons of Fe/sub 73.5/Cu/sub 1/Nb/sub 3/Si/sub 13.5/B/sub 9/ were annealed at 540/spl deg/C and at 950/spl deg/C r...

Zusammenfassung:In our work a reversible process for creating nanocrystalline Fe/sub 73.5/Cu/sub 1/Nb/sub 3/Si/sub 13.5/B/sub 9/ by annealing the amorphous ribbons was observed. The original amorphous ribbons of Fe/sub 73.5/Cu/sub 1/Nb/sub 3/Si/sub 13.5/B/sub 9/ were annealed at 540/spl deg/C and at 950/spl deg/C respectively as well as melted at 1200/spl deg/C. Such prepared samples were milled in a vibrational ball mill under the vacuum. The exponential law for decreasing the crystal size with the milling time was observed. The bigger the amount of the amorphous rest in material, the shorter is the time of milling for obtaining the requested crystal size.< >
