Professor Garritt Tucker has been awarded a three-year $183,000 National Science Foundation Division of Materials Research grant through the Metals and Metallic Nanostructures program for his project “Collaborative Research: Tailoring the Stability and Deformation of Nanocrystalline Alloys through Hierarchical Engineering”, that will be conducted in collaboration with Professor Jason Trelewicz at Stony Brook University.
Nanocrystalline metals are rapidly being recognized as a new class of engineering materials with advantageous mechanical properties, such as high strength and increased wear resistance. This research combines computational and experimental materials science to investigate a novel approach for improving the stability and mechanical behavior of nanocrystalline metals by introducing periodic non-crystalline regions into the crystalline matrix material. By understanding the stability and mechanical nature of these alloys, this activity assists in the development of a new generation of novel structural materials with tunable properties. Professor Tucker will employ large-scale high-performance computing architectures and novel numerical algorithms to study nanoscale materials physics that fundamentally govern metallic nanostructure behavior.
