Influence of Magnetic Annealing on Shear Modulus and Internal Friction of Fe sub 78 Si sub 10 B sub 12 Metallic Glass

摘要

Shear modulus and internal friction dependences on magnetic bias field were investigated. Considerable improvement of the piezomagnetic properties of Fe sub 78 Si sub 10 B sub 12 metallic glass was achieved by low-temperature (260 deg C) heat treatment in perpendicular magnetic field (12 kA/m). However, various samples from the same amorphous ribbon show largely different behavior versus magnetic field. The problem is discussed in the paper. (ERA citation 12:011626)
