Abstract
Observations on quenched-in resistivity in alpha brasses showed an apparent decrease in the activation energy of vacancy formation with increasing zinc content from a value of 0·85 eV for the analytically pure copper to 0·30 eV for the Cu-35% Zn alloy. This effect was attributed to the enhanced formation of zinc-vacancy pairs. A random distribution of zinc atoms in the lattice was noticed up to a concentration of 15% zinc content. Quenching was found to destroy the short-range ordering which appeared in annealed samples having higher zinc concentrations.
