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 ...
Temperature Variation of the Elastic Constants of Cubic Elements. I. Copper
(1954-09-08)
The ultrasonic pulse technique has been used in conjunction with a specially devised cryogenic technique to measure the velocities of 10-Mc/sec acoustic waves in copper single crystals in the range from 4.2°K to 300°K. The ...
