Los engineers from NASA have developed a “revolutionary metal“never seen what it is 1,000 times more durable than the one currently used in spaceships. The alloy, baptized with the name of GRX-810is already being tested in aerospace systems from high performance because it withstands extreme levels of heat, friction and stress. Thus, NASA wants to ensure that the components of the ships and the Reaction engines be more efficient y reliable in extreme conditions.
In addition to multiplying durability, the GRX-810 withstands 1,090 degrees Celsius and it’s more malleable y flexible than the materials currently used by the special agency. In particular, you can offer a endurance twice as large as current spacecraft components at high temperatures.
Long lasting performance
That means it not only offers more robustness, but rather endows the new metal with long-lasting performance. That is, the material is cost-effective, lightweight, and leads to higher efficiency of motors because they consume less fuel and they need a less maintenance.
Another of the ‘powers’ offered by the new metal is the tensile strength compared to existing alloys: bends and stretches up to three and a half times more than current alloys before breaking under stressexplain those responsible for the creation, engineers from the Glenn Research Center of NASA, in Cleveland.
3D printing, key
The development of the GRX-810 is complex. The easy part to understand is that it is achieved exclusively through the 3D printing. The complicated one is explained by its creators. “It is prepared from an alloy reinforced by oxide dispersion (ODS), which is generally used in environments of high temperaturesuch as turbines and heat exchange tubes. Due to the presence of ODS, the GRX-810 can withstand temperatures of over 1,090 degrees“. It is then that the particles of oxides to nanoescala of ODS are evenly distributed throughout the alloy by 3D printing.
Computational models instead of ‘trial and error’

To get a workable result with little evidence, the experts created computational models to simulate the thermodynamic performance of the material. Thus, they “quickly” predicted the optimal composition of GRX-810 at “much lower” costs, says Tim Smith, a member of NASA’s Glenn Research Center.
“With the classic techniques of ‘try and failure‘ It could have taken us years to create this new alloy.” “Now we can produce new materials faster and with better performance than before,” adds Smith.
