Due to their complex atomic environment, preferential chemical ordering, which is otherwise known as short-range order (SRO), has been proposed in various multicomponent alloys. However, it is difficult to predict the formation of SRO and its impact on deformation due to its various origins such as magnetic frustrations, strong electronic interactions, or formation of complexes with interstitial elements. Based on previous reports in binary alloys, we propose a simple parameter for predicting the degree of SROs in 3d transition metal-based complex concentrated alloys (3d CCAs). The resultant SRO-induced deformation mechanisms such as planar slip will be discussed via in-situ deformation studies using various scanning electron microscopy techniques. Our findings call for revisiting the classical understanding of the deformation behavior of 3d CCAs taking into account chemically ordered configuration effects.
