Abstract : The Engineering Foundation Conference on Processing and Design Issues in High Temperature Materials was held in Davos, Switzerland, 19-24, 1996. Approximately fifty participants represented academic institutions, industrial research laboratories and government organizations. The goal of the conference was to exchange areas of common concern among developers and users of high temperature materials of differing types, including superalloys, ceramics, intermetallics and composites. Levels of design ranging from atomic theory to processing techniques were covered in nine oral technical sessions and a poster session. The keynote lecture, entitled "Implementation Challenges for High Temperature Composites" was followed by 26 invited and 15 contributed papers, of which four were poster presentations. The participants were noteworthy for the wide range of their technical specialties. It was evident that many participants were exposed to relatively unfamiliar materials and topics as a result of efforts by the organizing committee to have an extremely diverse group of conferees. Since superalloys dominate current high temperature applications in the 800-1100 C range, it was considered to be important to discuss alloy design principles, microstructures and mechanical properties of potentially competitive materials such as ceramics and intermetallics, as well as their composites. Environmental effects on mechanical properties were highlighted; it was shown, for example, that water vapor can be detrimental to both intermetallics at low temperatures and ceramics at high temperatures. Oxidation of high temperature materials was another environmental issue of great importance that was discussed in several papers.
