We suggest that the maximum in Young's and the biaxial modulus observed for composition-modulated metallic superlattices arises from the same physical causes as the minimum observed in the shear modulus, namely the mutual attraction between the interfaces. We also suggest that anomalies similar to those in the elastic moduli do not exist in the elastic constants.
