| Abstract Scope |
Pure aluminum is used in various important products, while alloying aluminum with other elements is needed to achieve the mechanical properties, formability, and other performance specifications. The existence of elements in aluminum affects the forming behavior of metals. Especially, in severe plastic deformation, the distribution of alloying elements can change the motion of dislocations. Even for the same amounts, there can be a significant difference between the elements highly soluble (e.g. Mg) and those with significantly limited solubility (e.g. Ti and B) in base metal. In a previous study, a biaxial alternate forging system to allow continuous strain accumulations on the work-pieces of light-metal alloys using octagonal rod shaped dies was developed. This die system can characterize the formability limit by accumulating strains to the specimens. In this study, effect of Mg solute on microstructural evolution of aluminum during a biaxial alternate forging was investigated. |
