 | NASA-developed 3D-printable alloy can take the heat
A metallic alloy called GRX-810 -- developed by NASA and newly available to the commercial sector -- fills a big materials gap for printed parts. It is estimated that a part made of the superalloy could last up to a year at 2,000 F under stress loads that would crack any other affordable alloy within hours.

 | What is laser peening for metal components?
According to Curtiss-Wright, laser peening (also called laser shock peening) "drives deep plastic strain into a part that creates a high-magnitude residual compressive stress from 1 to 10 mm below the surface." This process involves hitting a part surface with a laser repeatedly through a stream of water, offering designers the ability "to surgically engineer residual compressive stress into key areas of components." Benefits include enhancements to fatigue strength, durability, damage tolerance, and resistance to stress corrosion cracking of critical metallic components.
