摘要：

A novel extruded Mg-5Bi-5Sn-1Mn alloy is developed and exhibits high yield strength (YS) of 446 MPa and ductility of 13.2%, resulting from the bimodal microstructure composed of coarse unDRXed grains with strong extrusion texture and dislocation storage capacity as well as ultra-fine DRXed grains (0.48 mu m).
