Abstract

The optical properties of α-brasses are interpreted with the aid of energy-band calculations of copper, and a description is given of the energy surfaces in these alloys. The observed behaviour follows closely that predicted by Friedel; the Fermi energy does not move appreciably in these alloys, but the bottom of the conduction band is displaced downwards in energy with increasing zinc concentration. Also, it is seen that this conduction band is filled up at a rate given by the rigid band model, and that the Fermi surface contacts the zone boundary at the point X, near the limit of the α-phase solubility.
