Abstract
The effect of aging on yielding, strain-hardening, and texture evolution of ZK60 alloys was investigated during uniaxial warm compression at various temperature and deformation rates. Solid-solution heat-treatments (T4) and aging (T6) affected the behaviors of flow curves. The aged samples had a higher level of yield stress and lower strain hardening rates than the solution heat-treated samples. Linear strain-hardening behavior was examined using a visco-plastic self-consistent (VPSC) model and electron backscatter diffraction (EBSD). Predictions of the flow curve, twinned volume fraction and texture evolution of ZK60 alloys were compared with experimental results. Linear strain-hardening of flow curves was related to the strong activation of tensile twinning, {101¯2}, along with slip systems. Most precipitates formed during aging consisted of Zn and Zr elements. The effect of the aging process on deformation modes and stacking faults was discussed based on transmission electron microscopy (TEM) and VPSC modeling.
