Abstract
Abstract—The bending-deformation behavior of rapidly quenched Co69Fe4Cr4Si12B11 alloy wires 0.1–1 mm in diameter, which are fabricated by the Ulitovskii–Taylor method, are studied. A correlation between the failure mechanism of a wire and its diameter and bending loading conditions is shown. It is found that wires up to 0.2 mm in diameter exhibit no bending failure. The wedge-type fracture is observed for wires 0.2–0.35 mm in diameter; wires more that 0.35 mm in diameter exhibit steplike fracture. The wedge-type fracture, a dense regular shear-band network, and vein- and corallike fracture are shown to correspond to the 100% amorphous state of wires. This combination of signs is observed for wires up to 0.4 mm in diameter.
