Dr. Kumar Ankit, an Assistant Professor of Materials Science and Engineering at SEMTE is seeking researchers for a FURI project/thesis that concerns computational modeling and simulations of instabilities in multilayered immiscible films.
Multilayered films are used in a variety of applications such as x-ray mirrors, magnetic recording media and heads, diffusion barrier, and wear resistant coatings. Retaining the thermal stability at elevated-temperatures or thermal cycling is crucial for exploiting their novel structural and functional properties in advanced engineering applications. However, exposure to extreme environments induces spheroidization of the layered structures that cause significant loss of mechanical strength and conductivity, ultimately resulting in failure. Comprehending the mechanisms of morphological evolution in multilayers is necessary for devising strategies by which thermal damage can be mitigated. The object of this FURI project is to leverage phase-field modeling and supercomputing techniques to numerically simulate the temporal spheroidization of multilayers in Cu-based immiscible films. A comprehensive understanding of the diffusion mechanisms that govern the morphological evolution in multilayers will enable us to devise strategies for mitigating damage. The deliverables will be the phase-field model, numerical simulations of morphological evolution and development of post-processing codes to characterize the computational results. Consistent with FURI stipend (~10 hrs week).
