High-cycle fatigue behavior of severe plastically deformed binary Zn-60Al alloy by equal-channel angular extrusion

► The ECAE almost completely changes the microstructure of the as-cast Zn-60Al alloy. ► The ECAE considerably improves fatigue performance of the as-cast Zn-60Al alloy. ► The fatigue properties of the ECAE processed Zn-60Al alloy vary with ECAE parameters. ► Basquin's law can be used to express the fatigue behavior of multi-pass ECAE alloy. ► The ECAE significantly changes the nature of the fracture characteristics.
