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 0.18 nm, which is about an eleventh of that in the complementary space.
