“…They used an ultrasonic interfer~metric meth'Od to detect smal1 wave·vel'Ocity changes in crystals stressed hydrostatically and uniaxially. Their success encouraged further studies on copper, such as effects of temperature and al10ying on the TOEC lJs1ne only nnlwxlal-<;:tTess measurements, Salama, and Alers (1967) determined the TOEC of copper at 29;). 77, and 4 K.

The elastic properties of copper have been compiled and reviewed. Polycrystalline elastic constants included are: Young's modulus, the shear mociululO, the bulk modulm, and PoislOon's ratio. Single·crystal constantlO of second·, third., and fourth·order are included. Over 200 refer· ences to the experimental literature are given. A few theoretical numbers are included. When suffieient data exist, hest values are recommended together with their standard errors. Effects on the elastic constants of tf'mperature, pressure, and mechanical (plastic) deformation are in· cluded. The Cauchy (central·force) relationships and the single·crystal-polycrystal relationship are also discussed.

“…Ultrasonic waves are highly sensitive to microstructural variations in materials and have been used extensively to investigate anharmonic effects in various metals and alloys [1][2][3]. A major focus of these studies is on the higher order elastic constants and their relation to the microstructure of the material.…”

“…Die Versetzungsdichte, die aus der Warmeleitfahigkeit ermittelt wurde, ist etwa fiinfmal hoher, als aus elektronenmikroskopischen Durchstrahlungsaufnahmen hervorgeht. Dies kann folgende Ursache haben: Nach Messungen von Salama und Alers [53] sind die Quadrate der nichtlinearen elastischen Konstanten, die in die GroI3e B (1) eingehen, im Temperaturbereich des fliissigen Helium8 zwei-bis dreimal hoher als die bisher zur Verfiigung stehenden Werte bei Raumtemperatur. Das Verhiiltnis der Versetzungsdichten, die aus der Warmeleitfahigkeit,smessung und der Elektronenmikroskopie erhalten werden, reduziert sich damit auf einen Faktor zwei.…”

Single crystals of Cu + 4.6 atyo Ga and Ni + 60 at yo Co were deformed in tension in intervals at various temperatures between 4 and 293 OK. After each deformation interval the lattice component xg of the thermal conductivity was determined between 1.3 and 25 O K . xg decreases with increasing flow stress due to the increase in dislocation density. I n weakly deformed crystals (stage I of the work hardening curve), xg is proportional to T2 between 1.3 and 10 OK. At higher degree of deformation (stage I1 and 111) xg is found to increase more rapidly than T* a t very low temperatures. These results are explained theoretically in terms of the deviations of the dislocation arrangements from randomness.
