ON DEMAND: GRX-810 and the future of AM-enabled high-temperature propulsion
| WATCH NOW |
NASA’s Dr Timothy M Smith and Dr Paul Gradl join us live to discuss GRX-810, the NASA-developed high-temperature Additive Manufacturing alloy for advanced propulsion systems.
For years, AM propulsion engineers have relied on legacy alloys such as Inconel 718, Alloy 625 and CoC – materials adapted for the process, not designed for it. GRX-810 changes that, retaining usable strength at extreme temperatures where conventional superalloys, and even single-crystal cast alloys, can fail.
In this webinar, the speakers will cover:
- Why GRX-810 matters for high-temperature propulsion
- What NASA’s hot-fire testing revealed
- How the alloy performs against legacy AM materials
- Key design and processing considerations for adoption
- Key applications, including rotating detonation engines and hypersonic vehicles
- How GRX-810 moved from NASA research to commercial availability
This session is designed for engineers, materials specialists and AM users interested in pushing thermal limits, developing next-generation propulsion architectures, or understanding how a new alloy moves from laboratory to flight hardware.
