Ultrafine Grain Development AZ91 Magnesium Alloy Through Friction Stir Processing: Mechanical Properties and Corrosion Resistance
This study introduces the Friction stir processing (FSP) of AZ91 magnesium alloy for grain refinement with a view to improve the mechanical and corrosion properties. The results of microstructural characterization show a considerable change in the grain size from 49.49 µm to 4.91 µm after FSP. This refining contributes...
