Аннотация: “Thick” rapidly quenched microwires 50-200 mm in diameter without a glass coating were produced by Ulitovsky-Taylor method from Co71Fe4Si10B15 and Fe31Co34Ni10Si10B15 alloys with high glass-forming ability. The strong (sB=3000 МPа) amorphous microwires have a high bend and torsion plasticity due to formation a surface small regular grid of the shear bands. The rubber-like behavior (“gum metal”) of microwires is found to be taken place under elastic tensile and torsional deformation. Two-stage crystallization of amorphous microwires is ascertained. The slope of hysteresis loop and values of saturation field HS and coercive force НС are risen with increase of microwire diameter.
