| description | In this study, commercial AZ31B magnesium alloy was used to compare the differences between the microstructure, texture, and mechanical properties of conventional solidification (as homogenized AZ31) and rapid solidification (as RS AZ31). The results demonstrate that a rapidly solidified microstructure leads to better performance after hot extrusion with a medium extrusion rate (6 m/min) and extrusion temperature (250 °C). The average grain size of as-homogenized AZ31 extruded rod is 100 μm after annealing and 4.6 μm after extrusion, respectively, but that of the as-RS AZ31 extruded rod is only about 5 μm and 1.1 μm, correspondingly. The as-RS AZ31 extruded rod attains a high average yield strength of 289.6 MPa, which is superior to the as-homogenized AZ31 extruded rod, and is improved by 81.3% in comparison. The as-RS AZ31 extruded rod shows a more random crystallographic orientation and has an unconventional weak texture component in <<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>11</mn><mover accent="true"><mrow><mn>2</mn></mrow><mo>¯</mo></mover><mn>1</mn></mrow></semantics></math></inline-formula>>/<<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>20</mn><mover accent="true"><mrow><mn>2</mn></mrow><mo>¯</mo></mover><mn>1</mn></mrow></semantics></math></inline-formula>> direction, which has not been reported yet, while the as-homogenized AZ31 extruded rod has an expected texture with prismatic <<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>10</mn><mover accent="true"><mrow><mn>1</mn></mrow><mo>¯</mo></mover><mn>0</mn></mrow></semantics></math></inline-formula>>/<<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mover accent="true"><mrow><mn>1</mn></mrow><mo>¯</mo></mover><mn>2</mn><mover accent="true"><mrow><mn>1</mn></mrow><mo>¯</mo></mover><mn>0</mn></mrow></semantics></math></inline-formula>>//ED. |
