U.S.-Japan Joint Seminar: Advanced Materials for Severe Service Applications/December 1990/Honolulu, HI

该奖项将支持7名美国研究人员参加将于1990年12月2日至7日在夏威夷火奴鲁鲁举行的美日联合研讨会“用于重要服务应用的先进材料”。讨论的主要主题领域是(A)复合材料，(B)断裂韧性，(C)低温和高温应用的合金，以及(D)材料行为。研讨会的主要合办者为康涅狄格大学冶金系Arthur J.McEvly教授和日本东京大学机械工程系Hiroyuki Okamura教授。上一次关于这一一般性主题的研讨会是在1986年举行的，也是在美日合作科学计划的赞助下举行的。当时，有人建议在被认为对未来技术至关重要的领域对材料进行进一步研究。在本次研讨会上，将审查这项研究的进展情况，并再次确定需要进一步研究和开发的领域，以提高性能和可靠性方面的设计能力。与会者和观察员将代表两国的各种学术、工业和政府研究机构。结构设计的进步取决于材料的可用性，这些材料能够承受强加给它们的要求。这些要求包括施加应力的性质以及材料使用的环境。随着运行温度的升高，可能需要使用非传统结构材料，如陶瓷和复合材料。其他方法可能包括使用保护性涂层作为热屏障或防止氧化或腐蚀。一些结构必须在低温下运行，这对所使用的材料提出了其他要求。在所有情况下，都必须考虑裂纹的行为，包括动态特性、检测、疲劳和应力腐蚀开裂。预计研讨会不仅将促进关于这些专题当前研究的国际交流，而且还将促进机械界和材料界专家在共同感兴趣的领域之间的交流。参与者将受益于分享新的成果，评估当前项目的进展，并为个人和合作研究绘制未来可能的方向。计划出版研讨会的会议记录。

This award will support the participation of seven U.S. researchers in a joint U.S.-Japan seminar on "Advanced Materials for Severe Service Applications," to be held in Honolulu, Hawaii, December 2- 7, 1990. The principal topic areas for discussion are (a) composite materials, (b) fracture toughness, (c) alloys for cryogenic and high temperature application, and (d) materials behavior. The principal co-organizers of the seminar are Professor Arthur J. McEvily, Department of Metallurgy, University of Connecticut; and Professor Hiroyuki Okamura, Department of Mechanical Engineering, The University of Tokyo, Japan. A previous seminar on this general topic was held in 1986, also under the auspices of the U.S.-Japan Cooperative Science Program. At that time recommendations were made for further research on materials in areas considered critical for future technology. At this present seminar progress in this research will be reviewed, and areas will again be identified where further research and development are needed in order to improve design capabilities in terms of performance and reliability. Participants and observers will represent various academic, industrial, and governmental research organizations in the two countries. Advances in structural design are dependent on the availability of materials capable of withstanding the demands imposed upon them. These demands include the nature of the imposed stresses as well as the environment in which the materials are used. As operating temperatures increase, the use of non-traditional structural materials, such as ceramics and composites, may be needed. Other approaches may involve the use of protective coatings to serve as thermal barriers or to guard against oxidation or corrosion. Some structures must operate at cryogenic temperatures, and this places other demands on the materials employed. In all cases consideration must be given to the behavior of cracks, including dynamic characteristics, detection, fatigue, and stress corrosion cracking. The seminar is expected to promote not only international communication regarding current research on these topics, but also communication between specialists in the mechanics community and in the materials community in areas of common interest. The participants will benefit from sharing new results, evaluating the progress of current projects, and charting possible future directions for individual and cooperative research. Publication of the proceedings of the seminar is planned.
