Abstract

The fatigue behaviour of melt-spun Fe78-xCrxSi10B12 and Fe77.5-xCrxSi7.5B15 (0≤×≤8) amorphous alloy wires is compared with those of HT steel wires. The wires were tested in a novel bend fatigue testing machine that imparts compressive to tensile stresses. Tensile strength and microhardness were also measured; these and the fatigue performance improved with the substitution of Fe by Cr. The fatigue performance of the glassy alloy wires was generally similar to that of HT steel wires when expressed on the basis of bend strain but inferior when expressed on the basis of bend stress. Fractography studies revealed differences in the fracture surface features for the amorphous wires, depending on the stress range amplitude. It was also observed that corrosion pits nucleated on the surfaces of glassy wires with zero or low Cr content and resulted in crack initiation at these points.
