High strength commercial AZ91D alloy with a uniformly fine-grained structure processed by conventional extrusion

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 pre...

Zusammenfassung: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.
