Title

Stabilizing Potential Super Alloys

Abstract

Superalloys are materials that have very useful properties, including things like superior mechanical properties, and better high temperature performance. A search for novel materials is always underway in an effort to maximize effectiveness of out materials. Computational methods have been developed to expedite that search by using Density Functional Theory from Quantum Mechanics to model materials that have never been created before. A set of proposed superalloys was found to be metastable, causing the desired properties to be lost after some time. This project explores the possibility of adding additional elements to the aforementioned alloys in an effort to stabilize the superalloy phase. This presentation explores the methods that will be used to model the alloys with the additional elements.
