Grain structure evolution during friction-stir welding of 6061-T6 aluminum alloy
Abstract
In this work, electron backscattered diffraction (EBSD) was used to examine the evolution of the grain structure during friction stir welding of aluminum alloy 6061-T6. In the entire FSW range studied, the microstructure evolution was found to be governed by continuous recrystallization. An increase in the welding temperature resulted only in microstructural coarsening.
