“…7): this is typical for Zener relaxation in alloys with atomic ordering [22]. Decrease in grain size increases the P3 peak relaxation strength and enhances high temperature IF background, while the presence of NbC particles increases the activation energy of the P3 peak [12] giving some arguments in favour of grain boundary sliding origin of the P3 peak. Heating of wq samples to temperatures below 600…”

Fe-Ga and Fe-Ga-Al alloys are studied by different mechanical spectroscopy techniques, conventional microscopy, DSC and dilatometry. Main contribution to amplitude dependent damping is assigned to magnetomechanical damping, which is very sensitive to structural state of alloys. Both temperature dependent thermally activated relaxation effects and effects due to phase transitions are discussed in terms of alloy structures and their ordering.K e y w o r d s : Fe-Ga, internal friction, damping, ordering

“…In contrast to systematic study of magnetic characteristics, very little is known yet on internal friction in Fe-Ga alloys [11]. After the paper [5], several studies of anelastic effects in Fe-Ga alloys were carried out [10,[12][13][14][15][16][17].…”

Structure, magnetostriction and damping properties are analyzed in Fe 82 Ga (18-x) Al x (x = 0, 5, 8, 12) alloys. Anelastic response of Fe-18(Ga+Al) alloys is studied as a function of temperature (from 0 to 600°C), frequency (from 0.01 to 200 Hz) and amplitude (from 0.0004% to 0.2%) of forced vibrations. The origin of the relatively high damping capacity of Fe-Ga-Al alloy at room temperature is checked by applying magnetic field and different heat treatment regimes. Substitution of Ga by Al in Fe-18%Ga alloys decreases magnetostriction and damping. Heat treatment of alloys influences the damping capacity of alloys more than variations of their chemical compositions. Thermally activated frequency and temperature dependent anelastic effects in Fe-Ga-Al alloys are analyzed and corresponding activation parameters for relaxation processes are evaluated. Internal friction effects caused by structural transformations are recorded and are consistent with the A2 → D0 3 → L1 2 reaction. Physical mechanisms for all anelastic effects are discussed.
