Abstract
Dislocation mobility in quasicrystals is calculated using basic thermodynamic and hydrodynamic equations. The dependence of the dislocation mobility on viscosity, vacancies and phasons is given. It is shown that the phasonic defects make the major contribution to the inverse mobility of the free segments of dislocations.
摘要
利用基本的热力学和流体动力学方程计算了准晶体中位错的迁移率。给出了位错迁移率与粘度、空位和声子的关系。结果表明，声子缺陷对位错自由段的反向迁移率起主要作用。
