Annealing of rare earth magnetostrictive co-precipitates of Jinzhong Fu

Precipitation of soil, so that the matrix composition optimized for bar Tb0.22Dyo. 66I-Ion35Fe1-95, XRD and composition analysis of knowing by the cubic Laves phase structure are REFe2 phase matrix contains only a small amount of rod-rich rare-earth phase, the magnetic field strength of 400kA / m, its more than 500X10'6 magnetostriction coefficient , low field magnetostriction is higher. 4 Conclusion References: ....
