ABSTRACT:
Introduction of beryllium into iron-boron base glassy alloys improves the thermal stability while substantially retaining the saturation moment and significantly reducing the saturation magnetostriction of the base alloy. The alloys of the invention consist essentially of about 6 to 18 atom percent boron, about 2 to 14 atom percent beryllium and about 72 to 85 atom percent iron plus incidental impurities.
