Grain refinement and mechanical properties enhancement of AZ91E alloy by addition of ceramic particles

Improved mechanical properties and structural uniformity of Mg-based alloys can be achieved by use of grain-refining additives prior to casting. Ceramic particles of α-Al 2 O 3 and SiC can serve as such additives to refine the microstructure of Mg–Al-based alloys. However, direct introduction of cer...
