There has recently been discussion on processing of magnesium alloys by equal channel angular extrusion (ECAE) to achieve a high elongationto-failure under superplastic tensile deformation. A two-step processing route was suggested to improve superplastic capabilities of such alloys. In this work, s
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 โผ1310% when using an initial strain rate of 2.0 ร 10
