Effects of Thermal Annealing and Pulsed Photon Processing on the Magnetomechanical Properties of the Amorphous Fe79.3P11s.2V2.5 Alloy

The effects of thermal annealing and pulsed photon processing on the structural transformations, AE effect, and internal friction in the amorphous Fe79,3P18.2V2.5 alloy are studied. The results demonstrate that annealing and pulsed irradiation in a magnetic field have a significant influence on the magnetomechanical properties of the alloy, whereas pulsed irradiation in zero magnetic field has little effect on these properties. The irradiation effect is shown to depend on the structural transformations of the alloy at temperatures far below its crystallization temperature.
