M. Polcarova et al., SR topography of plastically deformed Fe-Si bicrystals - observation in situ and post mortem, J PHYS D, 32(10A), 1999, pp. A109-A113
SR reflection topography was applied to study the interaction of slip dislo
cations with the grain boundaries in Fe-4at%Si bicrystals deformed by compr
ession. Three experimental settings with either a white or monochromatic be
am were used and the corresponding orientation contrast analysed. Dislocati
on transmission through the grain boundary was observed in bicrystals with
favourable geometry of the slip systems.
