Ultrafine-grained Ti–6Al–4V alloy with high mechanical properties in both strength and elongation was prepared by equal channel angular pressing and following pulsed electric current treatment. The mechanical properties of Ti–6Al–4V alloy were investigated by tensile tests at room temperature. Elong...
