| Abstract Scope |
This presentation establishes the evolution of mechanical properties of recently developed GRX-810 (32.15 Ni, 33 Co, 29 Cr, 1.5 Re in wt%) alloy across temperatures ranging from ambient to 1093°C. NASA’s Glenn Research Center developed the GRX-810 alloy for extreme thermomechanical environment applications. The promise of this novel alloy is the superior strength, oxidation resistance, and extensive improvement in creep performance compared to the conventional nickel-based alloys widely used at high-temperature applications. In addition to presenting high-temperature behavior, we also investigate the sensitivity of the mechanical behavior of GRX-810 to sample geometry from thin walls to bulk. Furthermore, the deformation mechanisms driven by microstructure and size are compared with Ni-based superalloys such as Haynes 214 and Haynes 282. |
