摘要
Icosahedral quasicrystals deform plastically by dislocation motion. The deformation behaviour can be modelled by simple equations of dislocation mobility, the damage of the quasicrystal structure and the kinetics of dislocation evolution, but fundamental questions are still discussed, like the mode of dislocation motion (glide or climb) and the role of phason defects.
