This patented nano-encapsulated aerogel technology was developed by engineers at the Johnson Space Center. Aerogel, nicknamed solid smoke, has been used in a variety of space missions for its properties as the lowest-density solid known.
A new method for heat treating friction stir welded plates made of 7X50 aluminum alloy reverses the deleterious effects of welding and restores the alloy’s mechanical properties. The method increases tensile and yield strengths, minimizes or eliminates stress corrosion cracking, and increases ductility over non-treated welded plates.
