U.S.-Czech Materials Research on Creep Deformation and Damage Mechanisms in Advanced Metal Matrix Composites

INT 9602022兰登这个由南加州大学的特伦斯·兰登博士和布尔诺捷克物理与材料研究所的瓦茨拉夫·斯克伦尼卡博士合作的美国-捷克材料研究项目将重点放在镁金属基复合材料上。兰登和斯克伦尼卡博士将与另一位捷克同事布拉格查尔斯大学的帕维尔·卢卡克博士一起研究这些复合材料的机械性能，特别是蠕变行为。蠕变实验将在南加州大学进行，使用两种由德国生产的先进镁复合材料挤压铸造。随后，这些蠕变试验结果将与布拉格拉伸试验和布尔诺使用定量金相进行的损伤评估实验所获得的数据相结合。总体而言，研究人员希望拓宽对镁基复合材料变形的基本理解。他们的结果可能对金属成形工业中使用的新加工技术有一定的指导意义。这个先进材料和加工项目通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在相互感兴趣和能力很强的领域汇集资源，从而实现了促进科学知识的计划目标。?？

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. ??
