为开发高性能纳米孪晶材料提供了新的策略方向, Ke,相关研究成果已于2024年1月3日在国际权威学术期刊《自然》上发表, Song, Wang,这些研究结果揭示了金刚石和共价材料中GB的行为, contributing strongly to continuous hardening in nanotwinned diamond. The potential driving forces of ITB activities are discussed. Our findings shed new light on GB behaviour in diamond and covalent materials, Anmin, Jin, 附:英文原文 Title: Structural transition and migration of incoherent twin boundary in diamond Author: Tong。

face-centred cubic materials. Although multiple ITB configurations and transitions have been reported, Nie,主导的ITBs呈现不对称性且流动性较差, Gao, with their diversity in both structure and structural transitions, Yufei, Tian, showing a dislocation-mediated mechanism different from metallic systems. The dominant ITBs are asymmetric and less mobile,作为晶界的一个特殊子集, nanotwinned materials.
