Key problems faced by society are rarely characterized as problems of science and technology; they are grouped as social, economic or political problems. However, it is clear that social, economic and political issues intersect, and that technological advance and innovation is at the heart of each intersection-sometimes causing the problems, but more often presenting solutions that elevate the human condition. The thesis of this presentation is that it is incumbent upon the university to ensure that each of its graduates has an understanding of technical issues which will allow them to participate fully in society and meaningfully in the dialogues which will lead to governmental policy decisions in the future. At Cal Poly we have developed a schema to address this need, built primarily around materials engineering topics. The proposed structure is true to the character of the institution and presents non-engineers with a real exposure to technology. Assessment results are presented and discussed.

This unique course is an ancestor to many of the "mechanical dissection" approaches to engineering education which are so very popular today. The paper highlights the value of the course as a culminating experience for the materials undergraduate. It treats the soliciting and selection of projects, the development of team approaches, the analysis of failures and the synthesis of failure hypothesis. The student's presentation of results are discussed, both written and oral. Creation of realistic mock "court-room" and "board-room" environments is treated. The use of case-study approaches in conjunction with modern educational technology is discussed. This presentation is meant to help others develop similar courses or help others create "failure analysis" modules to use in existing courses. I)

Nickel alloys used in regimes where microstructure and properties are altered dynamically present unique requirements. Exposure may alter properties with unexpected early failure. The Gleeble is a valuable tool for investigation and simulation of thermo-mechanical properties of an alloy in various regimes up to the threshold of melting. In this study, four regimes of temperature and strain rate were simulated in an argon atmosphere to both investigate and document normal and abnormal failure modes. Commercial Inconel 601 was tested in selected regimes and in two treatments (as received and strain aged). Next two exposed conditions (TEOS and Hydride) were tested. Slow strain-rate and high temperature produced brittle intergranular fracture. Exposure at elevated temperature to process gases reduced both strength and ductility in both TEOS and Hydride. TEOS exposure reduced reduction in area in the alloy significantly more than the Hydride exposure.
