| Abstract Scope |
The integration of experimental and theoretical techniques is strongly emphasized in the research group of Prof. Peter K. Liaw. On the experimental front, in situ heating with neutron scattering, neutron imaging, and scanning transmission electron microscopy (STEM) have played big roles in the study of high-entropy alloys (HEAs). This experimental work has been complimented by theoretical simulations of HEA atomic mixing behaviors, using techniques such as Monte Carlo and Molecular Dynamics simulations. The present talk describes how these techniques were used to investigate the microstructural evolution with temperature and time in the AlxCoCrCuFeNi alloys. Although the microstructural evolution appears quite complex, the major trends may be understood and modeled in terms of the redistribution of atoms on a simple lattice, producing coherent phase mixtures, similar to nickel-based superalloys. |
