The Co−Fe (Cobalt−Iron) system

The effect of chemical disorder on the magnetic anisotropy of strained Fe–Co films

“…There are two valleys corresponding to the BCC (x < 0.76) and FCC (x > 0.76) ground state, separated by a saddle point at x ¼ 0.78; a ¼ 2.66 Å . The calculated critical Co concentration of about 76% for the FCC-BCC transition is consistent with the known existence range of the BCC-like Fe-Co B2 phase up to about 75% Co and two-phase behaviour (FCC þ BCC) at higher Co concentration [20].…”

Cobalt silicide formation on a Si(1 0 0) substrate in the presence of an interfacial (Fe 90 Zr 10 ) interlayer

“…Fe was also found to be uniformly distributed in the Co layer with a concentration of approximately about 5-10%. According to the Co-Fe phase diagram [24] as much as 10% of Fe can dissolve into…”

Liquid phase separation and rapid dendritic growth of undercooled ternary Fe60Co20Cu20 alloy

“…The sample used in the DSC analysis has a mass of 35 mg. As illustrated in Fig. 2c, the typical DSC curves of ternary Fe 60 Co 20 Cu 20 alloy show that the first endothermic peak appears at 1195 K during the heating process, which was determined to be a solid-state phase transformation of α-Fe to γ-Fe [19,25]. The subsequent two endothermic events at 1360 and 1666 K are related to the melting processes of the Cu-rich and (Fe, Co)-rich phases, respectively, due to their different melting points.…”

“…Each sample had a mass of 1 g. As shown in Fig. 1, the selected alloy composition point was marked in ternary Fe-Co-Cu phase diagram [21,24,25]. To map this composition point to three corresponding binary phase diagrams, we can find that the highly undercooled Fe 60 Co 20 Cu 20 alloy is involved in the metastable immiscible gap of both Fe-Cu and Co-Cu binary alloys.…”
