TOWARDS THE UNDERSTANDING OF THE DEFORMATION MECHANISMS OF REFRACTORY COMPLEX CONCENTRATED ALLOYS EXHIBITING B2- TYPE ORDER
Abstract
The current proposal aims at conducting basic research on refractory complex concentrated alloys which are now considered as materials systems potentially able to compete with conventional nickel-based superalloys. Among the most promising of these alloys for high structural applications under extreme conditions are those exhibiting ordered precipitates are very attractive up to 1000 degrees C and will be at the heart of the current research. Of particular interest will be investigating the relationships between mechanical properties and underlying deformation mechanisms with a particular attention being paid to the influence of order on those mechanisms. Such an analysis is currently missing in the materials science community on these refractory complex concentrated alloys but is required to understand the mechanical behavior of these alloy systems. Furthermore, the detailed description of these deformation mechanisms is challenging and will provide essential information to improve the modeling and the design of future potential interesting systems. This proposal will provide support for the sabbatical period of Dr. Jean-Phillippe Couzinie of the University Paris-Est Cr´eteil and the Centre National de Research Scientific will work on the four thrusts above during his one-year sabbatical period at the Center for Electron Microscopy and Analysis at the Ohio State University. The proposed work will also take advantage of strong interaction with the Air Force Research Laboratory, Materials and Manufacturing Directorate.
