Compositionally complex alloys, often termed high-entropy alloys, are an intriguing new class of materials that can crystallize as single-phase solid solutions with simple crystal structures despite containing high concentrations of elements with very different crystal structures. Additionally, they can display a good combination of mechanical properties making them attractive for a wide range of applications. Based on our work on the CrMnFeCoNi alloy which exhibits an excellent combination of strength, ductility and fracture toughness at ambient to cryogenic temperatures, consistent with its deformation modes of planar dislocation slip and deformation-induced nano-twinning, we will examine compositionally modified variations of this material. We will show how their failure resistance develops in the same temperature range when compositionally triggered deformation mechanisms such as transformation induced plasticity (TRIP) or twinning induced plasticity (TWIP) are enabled and additionally compare their behavior to a similar alloy that contains a second phase.
