Impact of Annealing on Magnetic and Structural Features of FeCoSiBMoP Metallic Glass

Popis výsledku v původním jazyce

Magnetic behavior of Fe51Co12Si16B8Mo5P8 metallic glass prepared by a melt spinning technique is studied by magnetic measurements and room temperature transmission Mossbauer spectrometry. Mossbauer spectra were evaluated by the Normos program using distributions of hyperfine magnetic fields, P(B). The resulting ribbons were inspected in the as-quenched state as well as after annealing at temperatures of 200-550 C-circle for 1 hour. In the low temperature region, i.e., below the onset of crystallization, structural relaxation phenomena were unveiled. The onset of crystallization as derived from DSC and from XRD measurements differs by similar to 40 degrees. Traces of crystalline phases were observed by XRD after annealing at 525 C-circle while DSC gives T-x1 = 566 C-circle. Mossbauer spectrometry exhibits presence of crystallites only after annealing at 550 C-circle. Standard deviation and the mean hyperfine magnetic field values of P( B) distributions obtained from Mossbauer spectrometry monotonically increase with temperature of annealing. They are attributed to the modification in the short range order of Fe atoms environments.
