Molecular Dynamics Based Design of Ultra-High Strength Steels
Abstract
Ultra-high strength steels (UHSS) are of great interest to the defense and other numerous industries but the need for high contents of various costly alloying elements such as Tungsten, associated with expensive manufacturing processes make them unaffordable. Alternative lower cost UHSS such as ES-1 and AF96 have been developed; however, further improvement of their mechanical properties is critical to make them competitive against available commercial UHSS like AerMet-100. This project explores the current state-of-art developments in the area of atomistic calculations, especially Molecular Dynamics (MD) simulations as they pertain to the design of the UHSS. The goal is to thoroughly explore the current state of interatomic potentials available for MD simulations and their feasibility to be employed to further explore the mechanical properties across hyper-dimensional composition space of UHSS. The potentials reported in the literature will be collected and missing potentials will be road mapped for development.
