| Abstract Scope |
Friction stir processing (FSP) is a powerful solid-state processing technique to modify the local microstructure via severe strain and resultant temperature. Starting with a super-saturated solid solution, FSP will introduce dynamic precipitation along with recrystallization, providing a kinetic pathway and morphology evolution of precipitates that is different from their static aging counterpart. In this study, the dynamic precipitation behavior of AZ91 alloy during FSP is investigated in detail, emphasizing its differing characteristics at various processing conditions. Its difference from static precipitation, relationship with the concurrent dynamic recrystallization and implication on the mechanical properties will be discussed. |
