| Abstract Scope |
Recent research has involved the development of computational schemes (computational thermodynamics and phase-field modeling) to simulate the transformation pathways underscoring microstructural evolution in refractory complex concentrated alloys (RCCA). These are then to be coupled with crystal plasticity/finite element methods (CP-FEM) to provide predictions of mechanical properties. To ensure that these various models are physically relevant and as accurate in prediction as possible, it is necessary to make use of state-of-the-art methods of materials characterization to provide necessary mechanistic details for use in model development. Using the alloy Al1Mo0.5Nb1Ta0.5Zr1, whose microstructure usually consists of both the intermetallic compound with the B2 crystal structure and a bcc phase, the nature of the interfaces between the two phases, the ordering scheme in the B2 phase, and the deformation mechanisms operating in the two phases have been characterized. This research has been supported in part by the US Army Research Laboratory. |
