The Impact of Wrought Processing on Rare Earth–Magnesium Alloys
Wrought processing influences the microstructure and properties of rare earth-magnesium alloys significantly. This type of metalworking, which involves deformation at elevated temperatures, can enhance mechanical strength, ductility, and fatigue resistance in these alloys. The consequent microstructure often exhibits fine grains and uniform distribution of rare earth phases, leading to improved overall performance.
