Abstract Scope |
The development of advanced structural materials is key to the implementation of advanced nuclear reactor design concepts, as well as to the life-extension of light-water reactors. Central to the development of new structural material classes is the evaluation of thermal and irradiation creep properties. Traditionally, these properties are measured using bulk specimens held at temperature under static loads for long periods of time. However, recent advances in thermal and mechanical testing creates an opportunity for the accelerated assessment of small-scale specimens. Utilizing accelerator technologies, combined thermal, irradiation, and mechanical testing is performed on small-scale specimens to efficiently study degradation mechanisms and creep properties. Specifically, four Co-free Fe-based multi-principal element alloys (MPEAs), with potentially desirable thermal and mechanical properties for structural applications in nuclear environments, are evaluated. Results are related to alloy chemistry, microstructure, and irradiation damage. |
