Investigation of Fundamental Mechanisms for Multi-Scale Modeling of Complex Concentrated Alloys for Aircraft Structural Applications
Abstract
The principal objective of the proposed program is to investigate fundamental mechanisms related to phase stability/transformations, deformation, and oxidation of complex concentrated alloys (CCAs), including the sub-class of single solid solution high entropy alloys, for high temperature aircraft structural applications. This effort will focus on the application of multi-scale characterization and modeling tools towards the understanding of these fundamental mechanisms. While these novel CCA alloys hold a lot of promise for future application, there exist a lot of gaps in the fundamental understanding and knowledge base related to these concentrated alloys involving complex chemistries and microstructures. Hence the motivation for the proposed program. While there are an exponentially expanding number of CCAs being developed and investigated by numerous research groups worldwide, with wide ranging elements, phases, microstructures and properties, the present proposal will be focused only on those CCAs that can potentially be applied for high temperature structural applications of interest to the U.S. Air Force. Therefore, the group of CCAs to be investigated will involve microstructures consisting of the body centered cubic (bcc) and ordered B2 phases, and typically involve refractory elements. Additionally, fundamental mechanisms in FCC based CCAs, containing ordered intermetallic precipitates were also investigated.
