摘要
本文介绍了纳米晶金属中观察到的负Hali-Petch斜率和优异的软磁特性等令人感兴趣的材料物理问题,并扼要阐述了导致这些反常现象的机制和晶体缺陷的重要作用。
This article describes attractive problems in materials physics such as negative Hall-Petch slope and excellent soft magnetic behavior in nanocry-stalline metals.Fundamental mechanizms leading to these abnormal phenomena and the important role played by crystal defects are also briefly expounded.
