High Entropy Alloys (HEAs) is a new class of alloys which are composed of 5 or more elements with equal or near equal atomic weight with promising mechanical behavior such as higher specific yield strength. In this study a Continuum Dislocation Dynamics (CDD) framework is used to study the deformation behavior of High Entropy Alloys. In this framework, the dislocations are divided into three types, a positive, a negative and an immobile, and coupled evolution equations are employed to describe the complex interactions between the different types of dislocations. Furthermore, the effect of the lattice distortion is considered by introducing stochastic terms in the evolution equations. The effect of temperature, grain size, and residual dislocation density is investigated.
