Abstract Scope |
We present a methodology of designing high entropy alloys based on continuum dislocation dynamics multiscale modeling. The developed framework combines Fast Fourier Transform (FFT) and Continuum Dislocation Dynamics (CDD) to model the evolution of dislocation density in polycrystalline high entropy alloys. Experimental results are used to evaluate the critical model parameters and identify empirical relations between these parameters and important compositional related physical properties. These empirical models can be used in the design of new high entropy alloys with tailored mechanical properties. |
