Abstract
The microstructure, texture and mechanical properties of a quasi-single-phase Zn-0.5Cu (wt. %) alloy processed by high-pressure torsion (HPT) for up to 10 turns were investigated using electron backscatter diffraction (EBSD), Vickers hardness measurements and uniaxial tensile tests. The results show that during torsional straining there is dynamic recrystallization, subgrain refinement, a dissolution of ε – Zn4Cu precipitates and solid-solution strengthening. Monotonic deformation develops a strong local texture instead of the characteristic basal fiber texture. Sharp texture and misorientation angles for all grain boundaries of <30° causes significantly higher yield stress and ultimate tensile stress compared to processing of the alloy by equal-channel angular pressing.
