It has recently been found that in aluminum-based alloys, the change in the logarithm of the specific heat with the logarithm of the electron concentration is more than three times the value expected from free electron model considerations. This is not likely to be a result of band structure. We suggest that this experimental behavior is a direct consequence of the strong dependence of the electron–phonon mass renormalization of the specific heat on the electron concentration.

Electron Energy Loss

Two analytical techniques for the determination (within the limits of validity of the free electron model) of the absolute atom concentration (AAC) are reported in details. One of these may be useful for the determination of a AAC for chemical elements (e.g. hydrogen) which are not easy to detect. EELS is used.

State Changes

The coefficient γ of the electronic specific heat is calculated accounting, on the same footing, for the change in the band density of states and the change in the electron–phonon mass renormalization that occurs when small amounts of impurities are added to a pure metal. For alkali alloys it is found that the changes in the mass renormalization are more important than density of state changes.
