NASA has developed a new superalloy called GRX-810 that could lead to stronger, more durable parts for airplanes and spacecraft. SciTechDaily reports: GRX-810 is an oxide dispersion strengthened alloy. In other words, tiny particles containing oxygen atoms spread throughout the alloy enhance its strength. Such alloys are excellent candidates to build aerospace parts for high-temperature applications, like those inside aircraft and rocket engines, because they can withstand harsher conditions before reaching their breaking points. Current state-of-the-art 3D printed superalloys can withstand temperatures up to 2,000 degrees Fahrenheit. Compared to those, GRX-810 is twice as strong, over 1,000 times more durable, and twice as resistant to oxidation.
“This new alloy is a major achievement,” said Dale Hopkins, deputy project manager of NASA’s Transformational Tools and Technologies project. “In the very near future, it may well be one of the most successful technology patents NASA Glenn has ever produced.” GRX-810 was developed under NASA’s Transformational Tools and Technologies project, with support from the agency’s Game Changing Development Program. The peer-reviewed paper has been published in the journal Nature.
