Thermodynamic modeling was used to determine enthalpies of formation and other thermodynamic parameters describing glass forming ability of Fe-Co-TM (TM = V, Nb, Cr, Mo) alloys. FeCo-based alloys are considered as candidates for applications as high magnetic flux density materials due to their high magnetic saturation and low magnetic anisotropy. Nevertheless, mechanical properties, especially the lack of ductility, are their main weakness. Therefore, further optimization by vitrification, further heat treatment and alloying should be considered. As the most crucial step is the synthesis of amorphous precursors, discussion is concentrated on the effect of transition metal substitution on the glass forming ability. The highest glass forming ability was reported for Fe-Co-Nb alloys. It can be also noted that the driving force for vitrification can be improved by substitution of Fe by other transition elements, as glass forming ability parameter ∆P_HS reaches the lowest values for Fe-less compositions.

热力学模型用于确定形成焓和描述Fe-Co-TM（TM = V，Nb，Cr，Mo）合金的玻璃形成能力的其他热力学参数。基于FeCo的合金由于其高的磁饱和度和低的磁各向异性而被认为是用作高磁通密度材料的候选材料。然而，它们的主要缺点是机械性能，尤其是缺乏延展性。因此，应考虑通过玻璃化，进一步的热处理和合金化来进一步优化。由于最关键的步骤是非晶态前体的合成，因此讨论集中在过渡金属取代对玻璃形成能力的影响上。据报道，Fe-Co-Nb合金具有最高的玻璃成型能力。P _HS达到用于铁较少的组合物的最低值。
