| Abstract Scope |
Refractory alloys are developed for extreme temperature environments above the limit of conventional metals. AM refractory alloys have seen significant developments due to the ability of the process to produce near-to-net shape parts. However, new methodologies for evaluating printed materials' fitness for service must be developed because of the challenges associated with extreme temperature testing and oxidation levels. A thermomechanical simulator was modified to evaluate the mechanical performance of the materials across a broad range of temperatures. Special hardware was developed considering geometry for compatibility with the joule heating utilized by the system as well as the potential risk of damaging standard components of the chamber. Oxidation was limited by reaching a vacuum of 10-5 torr. The procedure enables rapid and affordable mechanical testing nearing the material’s melting point. C103, TZM, and Tungsten samples produced via L-PBF were tested in uniaxial tension at high temperatures up to 3000 °C. |
