摘要
The as-extruded AZ91D magnesium alloy processed by conventional extrusion exhibits a yield strength of 320 MPa, an ultimate tensile strength of 382 MPa and a fracture elongation of 13.8%, superior than most AZ91D alloys reported so far, which is mainly attributed to ultra-fine grains, sub-micron precipitates, and strong texture.
