Measurement of Equilibrium Concentrations of Vacancies in Copper
(2014-07-02)
The net added fraction of thermally-generated atomic sites, ΔNN, has been measured, during equilibrium heating to near the melting point, in a coarse-grained copper bar of 99.999% purity. The linear thermal expansion, ΔLL, ...
Annealing Kinetics of Voids and the Self-Diffusion Coefficient in Aluminum
(2014-01-20)
The annealing kinetics of voids in 99.9999 wt% pure aluminum were studied over the temperature range 85 to 209 °C in thin specimens by transmission electron microscopy. The isothermal shrinkage of individual voids was ...
Self-diffusion in aluminum at low temperatures
(2014-01-20)
Values of the self-diffusivity of pure aluminum in the temperature range 130∮ to 200° have been determined by measuring the rate of annealing of prismatic and faulted dislocation loops in thin foils of quenched 99.999 pct ...
