Microstructural and superplastic characteristics of friction stir processed aluminum alloys

Keywords and Phrases

Friction stir processing; Thermal stability


"Friction stir processing (FSP) is an adapted version of friction stir welding (FSW), which was invented at The Welding Institute (TWI), 1991. It is a promising solid state processing tool for microstructural modification at localized scale. Dynamic recrystallization occurs during FSP resulting in fine grained microstructure. The main goal of this research was to establish microstructure/superplasticity relationships in FSP aluminum alloys."--Synopsis, page iv.
