Correction to Yao, H.; Qiao, J.-W.; Gao, M.C.; Hawk, J.A.; Ma, S.-G.; Zhou, H. MoNbTaV Medium-Entropy Alloy. Entropy 2016, 18, 189

The authors wish to make the following correction to their paper [1].

Table 4. Relative atomic size difference, ${\mathsf{\delta }}_{rij}$, and modulus difference, ${\mathsf{\delta }}_{Gij}$, of the alloying element pairs.

${\mathsf{\delta }}_{rij}/{\mathsf{\delta }}_{Gij}$	Mo	Nb	Ta	V
Mo	0	−0.049/0.696	−0.049/0.621	0.036/0.901
Nb	0.049/−0.696	0	0/−0.084	0.085/0.243
Ta	0.049/−0.621	0/0.084	0	0.085/0.325
V	−0.036/−0.901	−0.085/−0.243	−0.085/−0.325	0

should be replaced by the following table:

The numbers in the previous table stand for $\frac{9}{8}{c}_i{\mathsf{\delta }}_{rij}/\frac{9}{8}{c}_i{\mathsf{\delta }}_{Gij}$, not for ${\mathsf{\delta }}_{rij}/{\mathsf{\delta }}_{Gij}$ ($c_i$ is the atomic percentage), so all the numbers are different to those in the new table. Considering the relative difference of the alloying element pairs can be intuitively demonstrated by ${\mathsf{\delta }}_{rij}/{\mathsf{\delta }}_{Gij}$, we suggest replacing the table. We apologize for any inconvenience caused to readers. The manuscript will be updated and the original will remain available on the article webpage.
