US-Czechoslovakia Materials Research on Creep and Cavitationat High Temperatures

美国-捷克斯洛伐克材料科学研究项目由南加州大学的Terence J. Langdon博士和捷克斯洛伐克布尔诺物理冶金研究所的V. Sklenicka博士共同完成。高温下的蠕变变形是许多工业应用中的一个重要问题，而在铜基合金等材料中，这一问题更为复杂，因为铜基合金容易产生广泛的内部空化，最终导致空化失效。研究人员将利用他们实验室在高温蠕变和空化破坏领域的丰富经验。他们将对选定的铜基合金进行高温蠕变试验，其长期目标是更全面地了解变形机制和晶界滑动在内腔发展中的作用。​该材料科学项目通过使美国和东欧的领先专家在共同感兴趣和能力强的领域结合互补人才和汇集资源，实现了推进科学知识的计划目标。

This U.S.-Czechoslovakia research project in materials science is between Dr. Terence J. Langdon of the University of Southern California and Dr. V. Sklenicka of Institute of Physical Metallurgy, Brno, Czechoslovakia. Creep deformation at high temperatures is an important problem in many industrial applications and the problem is compounded in those materials, such as copper-based alloys, which are prone to the development of extensive internal cavitation and ultimately to cavitation failure. The researchers will employ their laboratories' extensive experience in the areas of high temperature creep and cavitation failure. They will conduct high temperature creep tests on selected copper-based alloys with the long-term objective of obtaining a more complete understanding of the deformation mechanisms and the role of grain boundary sliding in the development of internal cavities. This project in materials science 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.
