基于结构相关的边界特性的最新知识，讨论了先进多晶材料的与边界相关的体积特性和性能的设计和控制。晶界特征分布（GBCD）作为一种新的微观结构因子被引入，是设计和控制多晶材料体性能的有力工具。结合与晶界有关的其他微观组织因素，讨论了织构与GBCD之间的关系。研究表明，织构与GBCD之间的关系可以为具有理想性能的多晶材料的晶界设计和控制提供重要线索。本文介绍了近年来通过控制织构和GBCD对脆性材料增韧的成功研究成果。讨论了功能材料晶界设计与控制的潜力和前景。
On the basis of recent knowledge of structure-dependent boundary properties, the design and control of boundary-related bulk properties and performance of advanced polycrystalline materials are discussed. The grain boundary character distribution (GBCD) which has been recently introduced as a new microstructural factor is shown to be a powerful tool for designing and controlling the bulk properties in polycrystalline materials. The relationship between texture and GBCD has been discussed in connection with other microstructural factors associated with grain boundaries. It has been shown that the relationship between texture and GBCD can provide an important clue to the grain boundary design and control for polycrystalline materials with desirable properties and performance. The present paper shows recent successful achievement of toughening of brittle materials by controlling texture and GBCD. The potential and prospective of the grain boundary design and control for functional materials are also discussed.
