Abstract
Magnetomechanical coupling coefficient as a function of magnetic bias field in Fe23.5Cu1W3Si15.5B7 alloy in as-quenched state and after annealing in vacuum for 1 h from 400 to 500°C were investigated.
The maximum values of the k coefficient were equal to 0.10-0.14 for as-quenched state and increased to 0.61 after annealing at 450°C. The results were somewhat worse than those with Nb instead of the W.
Nanocrystallization begins after annealing above 450°C and the magnetostriction rapidly drops and the magnetomechanical coupling practically vanishes after annealing at 520°C.
