Abstract:
In the present study we have investigated the time - and temperature dependence of the transition of as-cast metastable Fe-(9-33at.%)Ga ‘Galfenol’ alloys to the equilibrium state along with corresponding changes in their functional properties and anelastic effects that accompany these transitions. To characterize such a time-temperature-transition diagram we used both long-time isochronal annealing (up to 300 hrs) and instant heating treatments with different temperature protocols. In-situ neutron diffraction, XRD, DSC, VSM, HV, SEM-EBSD, Mössbauer and mechanical spectroscopy techniques were used.
