文摘

The influence of small additions of gallium and antimony on magnetic susceptibility of the bulk glass forming Co₄₇Fe_20.9B_21.2Si_4.6Nb_6.3 alloy was studied in a wide temperature range up to 1830 K by the Faraday鈥檚 method. The undercooling for all the samples was measured experimentally. Both Ga and Sb additions were found to increase liquidus and solidification temperatures. However, gallium atoms strengthen interatomic interaction in the melts, whereas antimony atoms reduce it.
