Impact of annealing on magnetic and structural features of FeCoSiBMoP metallic glass

Thermomagnetic Properties and First-Order Reversal Curve Analysis of Annealed Fe-Co-Si-B-Mo-P Alloy

“…The analysis of DSC characteristic recorded in the temperature range 300-1173 K for the as-quenched Fe 51 Co 12 Si 16 B 8 Mo 5 P 8 precursor shows two distinguished exothermic peaks which indicate presence of a two-step crystallization [7]. The primary and secondary crystallization temperatures were determined as 839 K and 963 K, respectively.…”

“…Microstructure and crystallization kinetics studies of the Fe 51 Co 12 Si 16 B 8 Mo 5 P 8 alloy are described in more detail in our previous papers [7][8][9]. The analysis of DSC characteristic recorded in the temperature range 300-1173 K for the as-quenched Fe 51 Co 12 Si 16 B 8 Mo 5 P 8 precursor shows two distinguished exothermic peaks which indicate presence of a two-step crystallization [7].…”

“…The maximum of a broad diffraction peak is positioned at the 2Θ angle of about 55 deg [7]. The X-ray diffraction pattern taken from the annealed sample shows the presence of several narrow peaks with low intensity.…”

“…The X-ray diffraction pattern taken from the annealed sample shows the presence of several narrow peaks with low intensity. They can be assigned to Fe-free crystalline phases [7] which start to appear even though the first crystallization temperature, as derived from DSC, is still not reached. As a consequence, modification of the magnetic microstructure can also be expected.…”
