Reduced grain boundary mobilities in pure iron

Reduced grain boundary mobilities of 344 boundaries in pure iron measured by a fitting method described in *Grain boundary mobilities in polycrystals*, *Acta Materialia* 191 (2020) 211-220. The first three columns are components of the Rodrigues vector (in the fundamental zone of the 3D Rodrigues space) of the misorientation of the boundary. Columns 4 to 6 are components of the inclination (grain boundary normal in crystal coordinates) in the crystal coordinates of the first grain. Columns 7 to 9 are components of the inclination in the crystal coordinates of the second grain. Column 10 is the reduced grain boundary mobility in the unit of μm2/s. This is the data used to plot Fig. 4 in the publication.
