SHAINERT'S METALLIC FIBER Russian patent published in 2006 - IPC C22C49/14 

FIELD: metallurgy; structures of the metallic fibers.

SUBSTANCE: the invention is pertaining to the field of metallurgy, in particular, to the structures of the metallic fibers (the metallic vulcanized fiber, the metallic wool, the metallic flaky structures) intended for the dispersive reinforcement of materials, in particular, concretes. The invention presents the metallic fiber made in the form of the planar stretched basis and supplied, at least, with two anchors. The metallic fiber additionally contains the through perforation within the interval of 5-43 % from the total area of the surface of the fiber. The anchors are made in the form of the crystallites of the metal clamped to the part of the surface of the planar stretched basis, and the planar stretched basis is made in the form of the stretched ellipsoid. At that the inner structure of the planar stretched basis has the gradient of phases along the whole depth from the amorphous phase at one of its surfaces up to the microcrystallic phase at the opposite to it surface. The invention allows to increase the service life of the metallic fiber in the capacity of the dispersive reinforcing material for the constructional material and the building materials under operating conditions conjugated with the alternating mechanical and the temperature effects.

EFFECT: the invention ensures the increased service life of the metallic fiber in the capacity of the dispersive reinforcing material for the constructional materials and the building materials under operating conditions conjugated with the alternating mechanical and the temperature effects.
