摘　　要：准晶材料具有与传统晶体材料不同的长程平移序,导致准晶中位错的结构及其运动的控速机制与传统晶体相比差别很大,因而表现出与传统晶体不同的塑性变形行为。本文详细阐述了准晶塑性微观机理的实验和数值研究成果及相应的各种塑性微观控速机制的理论模型。Because of the unique long-range order, the dislocation structure and its motion in quasicrystals are quite different from that in crystals which results in distinct plastic behaviors of quasicrystals. The present paper provided a comprehensive review of the experimental and numerical study on microscopic mechanism of quasicrystal plasticity and the various theoretical models about the rate-controlling mechanism.
