A ZK60 magnesium alloy was processed by equal-channel angular pressing (ECAP) for up to 8 passes at 473 K and the evolution of strength and microstructural parameters were determined using hardness testing and X-ray line profile analysis. The results show the subgrain size and twin boundary density

An extruded ZK60 magnesium alloy was processed by equal-channel angular pressing (ECAP) and then tested in tension at elevated temperatures. The results show the alloy is superplastic at a testing temperature of 473 K with an optimum ductility of ∼1310% when using an initial strain rate of 2.0 Γ— 10
