This is a grant for a collaborative research program between the University of Ancona, Ancona, Italy and the University of California at San Diego. The objective of the study is to produce very refined grain size to the nanoscale through severe plastic deformation. The University of Ancona has a grant from the Istituto Nazionale per la Fisica della Materia (INFM) for "Physical Aspects of Ultrafine Grained Aluminum Alloys," and this NSF grant is a mechanism to substantially enhance collaboration by permitting funding that is complementary to the INFM study. A major goal of the INFM study is to use equal channel angular (ECA) pressing of aluminum alloys as a means to produce nanoscale grain size aluminum alloys. The effort by the US team is directed towards understanding the specific mechanisms by which the severe plastic deformation leads to a refined grain size. The study is expected to alleviate the empiricism involved in the quest to produce very fine-grained alloys of commercial value. The UCSD group will utilize both the mechanical facilities at UCSD and the University of Ancona. Graduate students, postdoctoral scholars and faculty will participate in exchanges on long-term basis (three months to one year) between these institutions. The collaborative program is very complementary in scope, and will give an opportunity to enhance the research by taking advantage of the international expertise.This NSF project is co-funded by the Office of Multidisciplinary Activities, the Division of Materials Research (Metals Research) and International Office (Western Europe) as a Cooperative Activity in Materials Research between the NSF and Europe (NSF 02-135). This project is being carried out in collaboration with University of Ancona, Ancona, Italy.

这是意大利安科纳安科纳大学和加州大学圣地亚哥分校之间合作研究项目的一笔赠款。该研究的目的是通过剧烈的塑性变形产生非常细化的晶粒尺寸至纳米级。安科纳大学获得了国家材料研究所 (INFM) 的一项拨款，用于“超细晶粒铝合金的物理方面”，这项 NSF 拨款是一种通过允许与 INFM 研究互补的资金来大幅加强合作的机制。 INFM 研究的一个主要目标是使用铝合金的等通道角 (ECA) 压制作为生产纳米级晶粒尺寸铝合金的方法。 美国团队的努力旨在了解严重塑性变形导致晶粒细化的具体机制。这项研究预计将减轻在生产具有商业价值的超细晶粒合金过程中所涉及的经验主义。 加州大学圣地亚哥分校团队将利用加州大学圣地亚哥分校和安科纳大学的机械设施。研究生、博士后学者和教师将参与这些机构之间的长期（三个月至一年）交流。该合作项目在范围上非常互补，并将提供一个利用国际专业知识来加强研究的机会。该 NSF 项目由多学科活动办公室、材料研究部（金属研究）和国际办公室（西欧）共同资助，作为 NSF 和欧洲之间材料研究的合作活动（NSF 02-135）。该项目是与意大利安科纳的安科纳大学合作进行的。
