Comment on “Dependence of volume changes during solid solution formation and of volume size factor on solute volume, group number and crystalline structure by O. Coreño-Alonso, J. Coreño-Alonso, Intermetallics 2012; 22:142”

We comment on the derivation as well as the applicability of the equation used for the bulk modulus of substitutional alloys in terms of the bulk moduli of the pure end members.
