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

美国南加州大学的Terence Langdon博士和捷克布尔诺物理与材料研究所的Vaclav Sklenicka博士共同开展的美国-捷克材料研究项目将重点研究金属镁基复合材料。Drs。兰登和斯克莱尼卡，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。蠕变实验将在南加州大学进行，使用德国生产的两种先进的挤压铸造镁复合材料。随后，这些蠕变试验结果将与布拉格的拉伸试验和布尔诺的定量金相损伤评估实验数据相结合。总的来说，研究人员希望拓宽对镁基复合材料变形的基本理解。他们的研究结果可能会对金属成形工业中使用的新加工技术产生影响。这个先进材料和加工领域的项目实现了推进科学知识的计划目标，使美国和东欧的领先专家能够在共同感兴趣和能力强的领域结合互补的人才和集中资源。?？

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. ??
