We investigated the effect of high hydrostatic pressure on the normal
grain growth in 2-D aluminium strips. The activation volume for normal
grain growth is 1.35 cm3/mol, i.e., 0.15 of the atomic volume. It was
shown that high pressure strongly increases the fraction of low angle
boundaries in the polycrystal. We investigated also the effect of high
hydrostatic pressure on Al [100] tilt triple junction motion. The
research was modified by the fact that grain growth is connected with
triple junction motion. In the present case this is related to
extension of low angle [100] tilt GBs. The activation volume for
triple junction motion is 4.5 cm3/mol.

2-D grain growth, low-angle boundaries distribution, triple junction,
