摘要:

A new six-dimensional Burgers vector of dislocations in Al–Cu–Fe and Al–Pd–Mn icosahedral quasicrystals has been determined to be 1/2⟨11 – 200 – 2⟩ by means of defocused convergent-beam electron diffraction. The component of the Burgers vector in the physical space is parallel to a twofold axis with a magnitude of 0·18nm, which is about an eleventh of that in the complementary space.
