Crystallization of rapidly quenched ribbons on the base of Fe₈₂Si₂B₁₆ under isothermal annealing
The crystallization kinetics of the amorphous alloys on the base of Fe₈₂Si₂В₁₆ has been studied under isothermal annealing using magnetometric method. The apparent crystallization activation energy of Еₐ and Avrami exponent n have been determined. The admixtures of Ni and Мо have been shown to infl...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The crystallization kinetics of the amorphous alloys on the base of Fe₈₂Si₂В₁₆ has been studied under isothermal annealing using magnetometric method. The apparent crystallization activation energy of Еₐ and Avrami exponent n have been determined. The
admixtures of Ni and Мо have been shown to influence weakly on the values of Еₐ and n.
The apparent activation energy of crystallization for the ribbons produced using industrial
raw materials coincides within the experiment accuracy with that for the alloys of identical composition produced from chemically pure components. It has been also ascertained that the n value is determined mainly by the chemical composition of alloy rather than by the thickness of the rapidly quenched ribbon. |
