Phase Transformations in an Fe-Based Bulk Amorphous Alloy inside a Ball Mill

详细

The possibility of using a ball mill to obtain an amorphous state in bulk amorphous Fe_61.4Ni_3.6Cr_3.2Si_2.4Nb_7.8Mn_3.6B₁₈ alloy is studied. The presence of a metastable phase in the initial reagents allows the rate of amorphization to be notably accelerated with an almost full transformation to the amorphous state. Compared to a quench-hardened tape, however, the content of the amorphous state obtained via mechanical milling is distinguished by a reduced content of boron and therefore a lower temperature of crystallization.
