NASA-funded research has developed a new alloy with negative thermal expansion properties that can significantly improve the stability of space telescope structures, enabling more precise detection of habitable exoplanets by maintaining ultra-stable optical systems necessary for future missions like the Habitable Worlds Observatory.
A team of materials scientists from NASA, The Ohio State University, and HX5 LLC have developed a 3D printing process that produces an alloy called GRX-810, which is much more resistant to stress than other alloys currently in use. The process involves adding a dusting of yttrium oxide powder to each layer of ink made of a mixture of cobalt, nickel, and chrome particles. The new alloy lasted for 6,500 hours in a creep test, compared to current top materials that typically last approximately 10 hours.
