INTERNAL FRICTION OF ZINC SINGLE CRYSTALS UNDER IMPACT LOADING

Abstract
The internal friction measurements have been carried out on zinc monocrystals in the mode of a flexural vibration, in an attempt to compare the dislocation damping in the basal slip system with that in the second-order pyramidal slip system. We examined the effect of cold working by impact loading. A cold-work peak is observed to occur at about 230°K in the pyramidal slip systen. Differences in amplitude dependent damping in annealed and cold-worked specimens are researched in both slip systems, respectively.
