本文介绍了几种纯金属和合金的纳米和亚微米晶粒尺寸的严重塑性变形技术的制造，其结构表征的结果，并提供在室温和超塑性条件下的机械性能的数据。特别注意晶界缺陷结构和所产生的超细晶金属材料的力学行为之间的关系。(C)1997年Elsevier Science S.A.
This paper describes the fabrication of several pure metals and alloys with nano-and submicrometer grain sizes by severe plastic deformation techniques, the results of their structural characterization, and provides data on their mechanical properties at ambient temperature and superplastic conditions. Special attention is paid to the relationship between the defect structures of grain boundaries and the mechanical behaviour of produced ultrafine-grained metallic materials.
