NSF-CGP Science Fellowship Program: Role of Interface in High Temperature Deformation

小行星9404693 该奖项支持特伦斯G教授的国外旅行费用。Langdon先生于1994年和1995年访问了南加州大学材料科学与工程系，与京都大学工程系的Minoru Nemoto教授进行了两次为期三个月的合作研究。该研究计划的目的是集中在界面现象的作用，在确定的类型和程度的多晶塑性在高温下。 已确定了两个领域作为这项研究的初始阶段。研究工作将在晶粒尺寸非常小的金属合金的变形中进行。这些材料具有超塑性的能力，但界面的确切作用还不清楚。研究人员还将使用铝基合金研究金属复合材料中界面的性质和意义。这项合作将南加州大学的Langdon博士及其同事的机械测试专业知识与京都大学的高分辨率电子显微镜工作相结合，Nemoto博士担任高压电子显微镜实验室主任。 这项研究将使两个调查小组了解新的重要领域，因此将有助于加强两个地点的研究活动。 该奖项由日本基金会全球伙伴关系中心（CGP）根据NSF-CGP科学奖学金计划资助。 ***

9404693 Langdon This award supports the foreign travel expenses for Professor Terence G. Langdon, Department of Materials Science and Engineering at the University of Southern California, to enable him to make two visits, each of three months duration, in 1994 and 1995, to conduct collaborative research with Professor Minoru Nemoto of the Kyoto University Faculty of Engineering. The research program is designed to focus on the role of interface phenomena in determining the type and extent of polycrystalline plasticity at elevated temperatures. Two areas have been identified for the initial stages of this research. Work will be conducted on the importance of grain boundaries in the deformation of metallic alloys with very small grain sizes. These materials have superplastic capabilities, but the precise roles of the interfaces are not yet understood. The researchers will also investigate the nature and significance of the interfaces in metallic composites between there inforcement and the matrix using an aluminum-based alloy. This collaborative effort combines the mechanical testing expertise of Dr. Langdon and his colleagues at USC with high resolution electron microscopy work at Kyoto University where Dr. Nemoto serves as the Director of the High Voltage Electron Microscope Laboratory. The research will expose both teams of investigators to new and important areas and therefore will serve to strengthen the research activity in both locations. The award is funded under the auspices of the Center for Global Partnership (CGP) of the Japan Foundation under the NSF-CGP Science Fellowship Program. ***
