Abstract
The authors studied the influence of the peculiarities of fabrication technique by rapid solidification of metallic alloy from the melt on the hysteresis magnetic properties (HMP) and the quality of the surface for nearly-zero magnetostrictiveamorphous ribbons with composition Со58Fe5Ni10Si11B16 . It was found that the quenching rate (the linear velocity of quenching disk V) and the cast temperature Тр practically don’t affect on the HMP and on the magnitude of temporary recession of the initial permeability caused by the directional ordering. However, the quality of amorphous ribbons significantly changes: it improves by increasing of quenching rate (velocity V), and quality of ribbons deteriorates by increasing of cast temperature Тр . The authors gave the interpretation of discovered regularities. The conclusion is drawn that in the studied alloy, a “superfi cial” pinning of domain walls, caused by the internal tension which are generated by superficial defects, don’t defi ne the HMP level because of a nearly-zero magnetostriction. In this case these properties are defined by a pinning of domain walls inside the ribbon.
