A team of University of North Texas researchers developed a nanocrystalline alloy that may redefine the way materials are made in aerospace, energy, and other sectors.
Materials science and engineering professor Rajiv Mishra and UNT College of Engineering post-doctoral researcher Mageshwari Komarasamy created this divergent alloy while conducting experimental research on creep deformation theory, according to a UNT news release.
“Nanocrystalline alloys are inherently unstable at high temperature, but we found a way to get them stable and that is a major breakthrough.”

Creep deformation theory states that all solids are slowly and continuously deforming while under constant stress. However, the new nanocrystalline alloy maintains its strength and keeps its shape even at high temperatures.
To develop the alloy that is more stable at high temperatures, the researchers processed a metallic alloy using elements that don’t generally mix.
“Nanocrystalline alloys are inherently unstable at high temperature, but we found a way to get them stable and that is a major breakthrough,” Mishra said in the release. “These results will have a profound impact on how materials are designed for high-temperature applications such as power plants and engines.”

UNT hopes its cloud-based computer program called RE-PLAN will be able to solve equitable distribution issues that often accompany a speedy rollout. The technology, which uses sourced data to allow public health agencies to craft response plans, will be dispensed with an urgency to target special demographics communities, like people who have disabilities, don't speak English, and don't have cars.

Dallas political leaders and UNT Dallas officials were among the speakers at the opening. Hall of Famer Emmitt Smith purchased the property in 2019 through his real estate company, E Smith Communities, as a place to build and incubate talent. UNT Dallas has now joined Dallas College and other organizations in setting up programs at the renovated center.
