[Massalski 2]中的Co-V相图是从[1991 Smi]重新绘制的。三个中间相（Co 3V（21至31 at.% V），r（45至70原子% V）和CoV 3）的报告存在。Co_3V在1000 ℃以上具有L_12结构。然而，[1997年Nag]通过中子衍射表明，这不是一个稳定的相。在[Massalski 2]中绘制的Co 3V和相场的形状是不寻常的，因为它们在从0到> 1000 C的整个温度范围内具有几乎恒定的宽度。这种不太可能的情况在[2003 Bra]的Co-V相图中被解决了。计算的相图与已有的实验数据一致。然而，需要进一步的证实，特别是在低温下，实验相边界数据是不可用的（例如，共析分解温度r）。
The Co-V phase diagram in [Massalski2] was redrawn from [1991Smi]. Three intermediate phases (Co3V (21 to 31 at.% V), r (45 to 70 at.% V), and CoV3) were reported to exist. Co3V was shown to have the L12 structure above∼ 1000 C. However,[1997Nag] showed by neutron diffraction that this is not a stable phase. The shapes of the Co3V and phase fields as drawn in [Massalski2] were unusual because they had nearly a constant width in the entire temperature range from 0 to> 1000 C. This unlikely situation was dissolved in the Co-V phase diagram thermodynamically assessed by [2003Bra]. This calculated phase diagram is consistent with existing experimental data. However, further corroboration is needed particularly at low temperatures where experimental phase boundary data are not available (for example, eutectoidal decomposition temperature of r).
