项目摘要

INT 9602022 Langdon This U.S.-Czech materials research project between Dr. Terence Langdon of the University of Southern California (USC) and Dr. Vaclav Sklenicka of the Czech Institute of Physics and Materials, Brno, will focus on magnesium metal matrix composites. Drs. Langdon and Sklenicka, together with another Czech colleague, Dr. Pavel Lukac of Charles University, Prague, will examine mechanical properties, specifically the creep behavior, of these composites. The creep experiments will be conducted at USC using two advanced magnesium composites produced in Germany by squeeze casting. Subsequently, these creep test results will be integrated with data obtained from tensile testing in Prague and damage assessment experiments in Brno using quantitative metallography. Overall, the researchers expect to broaden fundamental understanding of the deformation of magnesium-based composites. Their results may have implications for new processing techniques used in metal forming industries. This project in advanced materials and processing fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool resources in areas of strong mutual interest and competence. ??

INT 9602022 Langdon 这个美国-南加州大学（USC）的Terence Langdon博士和捷克布尔诺物理与材料研究所的Vaclav Sklenicka博士之间的捷克材料研究项目将重点关注镁金属基复合材料。兰登博士和斯克莱尼卡博士，以及另一位捷克同事，布拉格查尔斯大学的帕维尔·卢卡奇博士，将研究这些复合材料的机械性能，特别是蠕变行为。蠕变实验将在USC进行，使用两种在德国通过挤压铸造生产的先进镁复合材料。随后，这些蠕变试验结果将与从布拉格拉伸试验和布尔诺损伤评估实验中获得的数据进行整合，使用定量金相学。总的来说，研究人员希望扩大对镁基复合材料变形的基本理解。他们的研究结果可能对金属成形工业中使用的新加工技术有影响。这个先进材料和加工项目实现了促进科学知识的计划目标，使美国和东欧的领先专家能够在具有强烈共同利益和能力的领域联合收割机互补人才和资源。 ??
