Abstract

The basal stress-strain behavior, dislocation density, and strain rate sensitivity of the flow stress were measured at room temperature on single crystals of zone-refined zinc, 99.999 pct Zn, and zinc containing 0.0025 and 0.02 wt pct Al. No significant change in the strain rate sensitivity of the flow stress occurs with the addition of aluminum. Changes in dislocation substructure and nonbasal dislocation density were observed with the addition of aluminum. The effect of aluminum on the basal stress-strain behavior is explained in terms of changes in nonbasal dislocation density which determines the separation distance of junctions between basal and nonbasal dislocations. The onset of basal slip is associated with the breaking of attractive junctions. The change in basal dislocation density was found to be proportional to the one-third power of the plastic shear strain, independent of purity.
