Meanwhile, the existence of crystal defects renders the material performance a variety of changes. Understanding the laws of the formation and evolution of defects is of great significance for material design, processing control and failure analysis. This course focuses on four types of typical microscopic defects, i.e. point, line, planar (including surface) and volume defects. Starting with the review of fundamental knowledge of crystallography (symmetry group, crystal space lattice, crystal diffraction effect, etc.), the classification, formation and motion of defects, as well as their effects on material performance will be expounded. Combining with the study of characterization of defects and its typical applications, students will learn to make use of the advantages of defects and avoid its disadvantages, deepen the understanding on the 'structure-texture-performance' relationship and form the ability to use the relationship flexibly
