Researchers at Idaho National Laboratory have discovered how to extend the useful life of superalloys by thousands of hours by employing a unique recipe of heating and cooling to create a microstructure that can withstand extreme heat. The discovery could improve materials performance for electrical generators and nuclear reactors.

An excerpt:

“The key is to heat and cool the superalloy in a specific way. That creates a microstructure within the material that can withstand high heat more than six times longer than an untreated counterpart.” 

Dr. Subhashish Meher, INL postdoctoral researcher in Materials Science and Engineering

“We came up with a way to make a superalloy that is much more resistant to heat-related failures. This could be useful in electricity generators and elsewhere,” said Subhashish Meher, an INL materials scientist, lead author of a new Science Advances paper describing the research.
