摘要	Microelement B is widely added into almost all commercial superalloys because B contributes to strengthening grain boundaries at high temperature during service. Generally, B is present in two different forms. Besides the solute state in matrix, B tends to react with transition elements at high temperatures, giving rise to various borides including M2B, M3B2 and M5B3 phases. An accurate knowledge of the microstructural characterizations of these borides is of great importance for a better understanding of the structure-property relationship and designing materials with improved properties. By means of various advanced techniques based on the aberration-corrected transmission electron microscopy (TEM), microstructural features of above borides have been systematically investigated. Various defect features which were controversial in the past have been clarified. In this paper, after a brief review on the studies of borides, the atomic- scale information on the microstructural features has been presented. Finally, some prospects for future studies have been proposed.
