Enhanced mechanical properties were achieved in the rolled ZK60 Mg alloy sheet by pre-equal channel angular pressing (ECAP). Pre-ECAP fabricated fine microstructure and consequently led to a good ductility in the ZK60 alloy. During the subsequent rolling, the grains were further refined and more dislocations were activated inside the fine grains that effectively increased the work hardening and the strength of the alloy. The typical rolling basal texture was suppressed by the initial ECAP texture that helped for both of the rolling formability and ductility of the alloy.
