Using a 3D printing technology, NASA engineers have just produced a new metal alloy that significantly enhances the strength and longevity of components and materials used in aviation and space exploration.

Alloy GRX-810, an oxide dispersion strengthened (ODS) alloy, is more malleable and can survive more than 1,000 times longer than current state-of-the-art alloys. This is a significant improvement over current alloys. Aerospace components for high temperature applications, such as those inside aircraft and rocket engines, may now be constructed using these new alloys since ODS alloys can resist tougher temperatures before breaking

Dale Hopkins, deputy project manager of NASA's Transformational Tools and Technologies project, remarked that the tiny oxide particles express the amazing performance advantages of this alloy.

In order to create ODS alloys for these harsh settings, it is very difficult and costly. Researchers at NASA employed computer models to figure out the alloy's composition before moving on with development of NASA Alloy GRX-810. Nanoscale oxides were then distributed throughout the alloy via 3D printing, which enhanced its high-temperature characteristics and prolonged its service life. To put it another way, the new manufacturing process is more cost effective, time efficient, and environmentally friendly.
