Abstract
A study was made of the piezomagnetic and elastic properties of scrolls of Metglas 2605 SC, used as an acoustic transducer element. This study involved quasi-DC magnetic induction measurements and ultrasonic complex plane analysis of scrolls of various annealing histories. An optimum effective magnetomechanical coupling coefficient. K(eff), of 0.75, was found. The best magnetomechanical response in air obtained for metallic glass scroll during the study was for the unconsolidated case. However, preliminary experiments have shown that structural weakness and corrosion problems are significant when using the unconsolidated scrolls in water.
