(Summary description)Grain Boundaries and Defects in Nano (Micro/Nanomechanics) : Nano solid materials are three-dimensional block-like materials that consist of particles with particle sizes ranging from 1 to 100nm. The basic composition of nano solid materials (Micro/Nanomechanics) is the interface between nanoparticles and particles. Interfaces in physics do not refer to geometrical interfaces, but to a thin layer (micro-nano mechanics) whose surfaces have different properties from the substrates on either side. All interface phenomena exist because the atoms at the interface of an object are stressed differently from the atoms inside it, and therefore their energy states are different. In conventional coarse-grain materials, grain boundaries are only surface defects. For nanomaterials (micro-nano mechanics), grain boundaries are not only surface defects, but more importantly, a unit that constitutes nanomaterials (micro-nano mechanics), namely grain boundary unit. Nano - solid materials (micro - nano mechanics) have become one of the basic structures and have an impact on the special properties of nano - solid materials. Gleiter proposed in 1987 that the arrangement of atoms on the interface of nanometer micrograins is neither long-range ordered nor short-range ordered, but has a highly disordered gas-like structure. It is believed that the interface of nanomaterials (micro-nano mechanics) is arranged in an orderly manner, which is not different from that of coarse-grained structures. However, further studies show that the ordering of the atomic arrangement of interface elements is local and conditional, which mainly depends on the spacing of interface atoms and the size of particles. If the arrangement of atoms is locally ordered, the arrangement of interface tuples is reversed and disordered. The atomic structure of the grain boundaries of nanomaterials (micro-nano mechanics) is difficult to unify with a single model. Nevertheless, we still believe that the grain boundary structure of nanomaterials (micro-nano mechanics) is not fundamentally different from that of ordinary coarse grains. The shortcoming is that the actual crystal structure deviates from the ideal region. In the nanomaterial structure, the translation period is seriously damaged, the interfacial atomic arrangement is disordered, and the atomic coordination number is not complete, which leads to the increase of interfacial defects. In addition, the lattice constant increases or decreases after the nanometer powder is extruded into blocks, and the change of lattice constant increases the defect. The above is the plasma surface treatment equipment manufacturers on the mechanical properties of nanomaterials, I hope to help you.
