Preparation of a single-phase Mg–6Zn alloy via ECAP-stimulated solution treatment

The solution of the intermetallic phase and the homogenization of composition are important for Mg alloy biomaterials. A single-phase Mg–6Zn alloy with the average grain size of about 20 µm was prepared by ECAP processed for six passes at 320 °C. It indicated that the ECAP could significantly promote the process of solid solution in Mg–Zn alloy. The results showed that complete dissolution of the intermetallic phase improved the corrosion...
