Abstract
When β Au-Cd is quenched from a high temperature, a large increase in resistivity results. The amount of quenched-in resistivity was measured as a function of quench temperature and an energy of formation of 0.38 eV was obtained for the associated defects. The isothermal annealing of the quenched-in resistivity was studied at a number of temperatures. The process appears to have an incubation period and an activation energy for motion of 0.58 eV. Possible explanations are discussed; the quenching-in of lattice vacancies is considered to be the most likely source of the effect. On the basis of Jongenburger's theoretical estimates of the resistivity arising from vacancies in gold, it is estimated that about 0.7% vacancies are frozen in after quenching from 450°C.
