Shear stress – shear strain curves of 0.14 at.%Ti alloyed Zn single crystals were measured in compression at different temperatures and shear strain rates. The work‐hardening coefficient for basal slip increases with decreasing temperature and increasing shear strain rate. The work‐hardening characteristics are compared with those reported for Zn single crystals with different constituents and purities. It is discussed with respect to the interaction of dislocations with dislocations, vacancies, vacancy agglomerates and solute atoms. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
