摘要

Samples of rapidly -quenched ribbons and wires with a diameter of metal core of d_c= 50-200 μm within the ternary eutectic system Fe_(75)Si_(10)B_(15)-Co_(75)Si_(10)B_(15)-Ni_(75)Si_(10)B_(15) were obtained by the melt spinning and Ulitovsky-Taylor methods. The liquidus surface and crystallization surface of the amorphous alloys were constructed on the basis of the results of investigations of the thermal, mechanical and magnetic properties of the system alloys; the concentration ranges of amorphous alloys with various crystallization mechanisms and the ranges of amorphous alloys with the positive and negative Villari effect were determined. The concentration range of compositions favorable for obtaining amorphous wires with high glass-forming ability was determined. The comparative study of the structure and properties of the "thick" wires samples was carried out for two models alloys: Co_(71)Fe_4Si_(10)B_(15) and Fe_(31)Co_(34)Ni_(10)Si_(10)B_(15). It was found that the wires possess a new complex of high strength, ductile, elastic, and soft magnetic properties. The prospects for application of "thick" ferromagnetic amorphous wires associated with the development of new types of structural and functional materials were considered.
