Refractory high-entropy alloys (RHEAs) and complex concentrated alloys (RCCAs) are among the most studied materials in the metallurgical field. They own microstructures based on BCC structure, mainly, but could also exhibit B2 order when aluminum is added. Even if they are considered as promising structural materials for high temperature applications, some basic challenges have still to be addressed. The understanding of the deformation mechanisms is one of these. Hence, the present talk will first provide an overview on the properties of RHEAs and RCCAs based the analysis of the existing data from the available literature. The emphasis will then be put on recent observed deformation mechanisms bringing new insight of the mobility of dislocations in such complex materials. The influence of the presence of B2 order will also be analyzed in details.
