Ultra-High Temperature Materials Testing Equipment

The following main pieces of equipment are requested: • Mechanical load frame(s) (up to 3 frames) for static, quasi static and cyclic mechanical loading. The load frame and/or load frames will have the mechanical infrastructure, control systems, and software capable of supporting numerous standard mechanical tests, specifically: tensile, compression, low cycle fatigue, ratchetting, creep, creep fatigue, crack growth in fatigue , and crack growth in creep. The load frame(s) should include several load cells with a maximum capacity of 100 kN (unless justified otherwise), fixtures and gripping solutions for standard geometry specimens of the material families of interest at ultra high temperatures: refractory metallic alloys, ceramics, and ceramic-matrix composites. The load string must be capable of operating up to the required temperature for at least one test, with the understanding that fixtures are consumable when operating at these temperatures. The load frame(s) should have appropriate test control systems (e.g. to control for strain on the sample at temperature) and sufficient working space to permit the insertion of vacuum and heating systems. • A vacuum system compatible with mechanical testing at ultra high temperature. If there are multiple load frames then the single vacuum system (or the load frames) must be mobile to allow the vacuum system to be used by different load frames at different times. There must be ports for test control, optical ports for the data-rich diagnostics and their calibration and additional ports to allow future flexibility in diagnostics. • A gas introduction system to allow alternative atmosphere testing. • A heating system to allow sample test temperatures up to 2,500 °C and above for the material families of interest. The heating system must not limit the line of sight for the data-rich diagnostics. • An appropriate cooling system to protect the load cell and fixtures, where required. • A high spatial resolution IR camera and/or bolometer for spatially-resolved temperature measurement.
