MECHANICAL AMORPHIZATION OF THE FE73.5CU1NB3SI13.5B9 ALLOY

In our work a reversible process to creating nanocrystalline Fe73.5Cu1 Nb3Si13.5B9 by annealing the amorphous ribbons was observed. The origi nal amorphous ribbons of Fe73.5Cu1Nb3Si13.5B9 were annealed at 540-deg rees-C and at 950-degrees-C respectively as well as melted at 1200-deg rees-C. Such prepared samples were milled in a vibrational ball mill u nder the vacuum. The exponential law for decreasing the crystal size w ith the willing time was observed. The bigger the amount of the amorph ous rest in material, the shorter is the time of milling for obtaining the requested crystal size
