| 英文摘要 | Quenched Fe-18 at.% Ga with high magnetostrictive properties has a peak (P-wq) in temperature-dependent internal friction (IF) spectrum near 320 degrees C, which disappears for both as-cast and furnace-cooled alloys. However, the mechanism of this peak is not well understood. In this investigation, the behavior and mechanism of this peak were systematically studied. It is found that the P-wq appears when the sample is quenched from a temperature higher than the critical temperature of the order-disorder phase transition and disappears when annealed at 300 degrees C for 1 h. The P(wq )becomes gradually more apparent as the Ga content increases from below similar to 18 at.%, and the P-wq almost disappears when the Ga content equals 23 at%. Combined with deformation and XRD studies, the P-wq does not originate from the vacancies and dislocations produced by the high-temperature quenching process or a phase transition from D0(3) to L1(2), and potential formation mechanisms for the P-wq may originate from the transition of Ga-rich Guinier-Preston (GP) zones to D0(3) structures or lattice relaxation related to Ga-rich GP zones.
