TL;DR: In this paper, a design strategy based on overall valence electron concentration (OVEC) is developed, and a coherent D022 superlattice (noted as γ″ phase) with superior strengthening effect is designed.

TL;DR: In this article, the authors designed a Ti38V15Nb23Hf24 refractory high-entropy alloy that exhibits >20% tensile ductility in the as-cast state, and physicochemical stability at high temperatures.

TL;DR: In this article, the authors review the most recent research momentum regarding the formation mechanisms (elemental segregation, dislocation cell and oxide inclusion), the kinetics of the size and morphology, the growth orientation and the thermodynamic stability of these cellular structures by taking AM austenitic stainless steel as an exemplary material.

TL;DR: ARefractory high-entropy alloy was designed with the composition chosen based on the natural-mixing characteristics among refractory elements; this alloy demonstrates good tensile ductility in the as-cast state and physicochemical stability at high temperatures.

TL;DR: A recent overview of the research activities on metastability in high-entropy alloys can be found in this paper, where the authors categorize the past research on the topic into two groups based on their focus, namely compositional and structural stability.
