After sixteen successive passes of equal channel angular pressing (ECAP), kinked 18R-LPSO phase and refined DRX grains were developed in Mg94Y4Zn2 alloy. Simultaneously, nano-sized 14H micro cells and Mg24Y5 particles were dynamically precipitated. Owing to the above microstructure characteristics, the 16p-ECAP alloy exhibited outstanding mechanical property with compressive strength and fracture strain of 611 MPa and 20.1%, respectively.
