Riassunto

Advances in industrial technologies and improved performance of constructional materials are interdependent and have become of increasing concern in recent years. This Conference aimed to - provoke discussion of the limits towards which high temperature alloys properties can, ultimately, be developed, identify the resulting R&D requirements and design developments. Following a key-note paper concerning the relation of current capabilities to requirements for gas turbines the conference was structured into 3 sessions which examined: * the theoretical?ldpracticallimits for HT Alloys, * the potential for development in alloys and processing, * engineering considerations. Finally, feeling perhaps the approaching "wind of change"??1s Conference on remaining alloy potential was wound up with a paper entit1ed "The potential?ld problems ofEngineering Ceramics". The different sessions each included a number of invited papers followed by a series of posters and were concluded by a presentation of a "synthesis" by a sess10n rapporteur and general discussion. This structure is retained in the proceedings, including the discussion points in those cases where?le authors have provided written answers to questions raised.
