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, ...
Temperature Dependence of the Elastic constants of Cu, Ag, and Au above Room Temperature
(1966-02-16)
The adiabatic elastic constants C44, 1/2(Cll-C12), and 1/2(cll+C12+2c44) have been measured for copper,
silver, and gold over the temperature range from 300° to about BOO 0K using the conventional ultrasonic
pulse-echo ...
Measurment of Equilibrium Concentrations in Aluminum
(1959-07-31)
Measurements of change in length and change in lattice parameter were made at identical temperatures on 99.995% aluminum in the temperature range 229 to 656°C. Length changes, ΔL, were measured on an unconstrained horizontal ...
