Grain boundary character in samples of Zr701 annealed at two different temperatures has
been investigated in terms of lattice misorientation. The main difference between the two samples
was the extent of grain growth post-recrystallization. The textures were typical for the material.
Differences between the texture-based misorientation distribution function (T-MDF) and the
microstructure-based MDF (M-MDF) revealed significant preferences for certain grain boundary
types, notably those with <11-20> rotation axes.
