Abstract
The evolution of SZ and thermomechanically affected zone (TMAZ) microstructures during
single-pass and multi-pass FSP by rectangular and spiral raster processes will be summarized.
Microstructures produced by thermomechanical simulations will be compared to those produced during
FSP. The distortion of microstructure constituents in thermomechanical simulations may be applied
to estimation of SZ and TMAZ strain distributions in the initial FSP pass. Recrystallization in the
primary α constituent is initiated at κiv (Fe3Al) particles prior to their dissolution during
straining.
