Processing and Mechanical Properties of Ti<sub>2</sub>AlC MAX Phase Reinforced AE44 Magnesium Composite

AE44 alloys and nanolaminated Ti<sub>2</sub>AlC particle-reinforced AE44 magnesium composites were synthesized by stir casting techniques and textured by hot extrusion methods. It was found that lamellar Al<sub>11</sub>RE<sub>3</sub> precipitates spheroidized with...
