## Description

- description: 'Refractory ceramic materials are critical for applications in extreme
    high temperature environments. Refractory high-entropy ceramics belong to this
    class of materials and show great potential due to their remarkable combination
    of properties. Traditionally, increasing compositional complexity and chemical
    diversity of high-entropy ceramics whilst maintaining a stable single-phase solid
    solution has been a primary design strategy for developing new ceramics. Here,
    we unveil an alternative strategy based on deviation from conventional equimolar
    composition towards non-equimolar composition space, enabling tuning the metastability
    level of the supersaturated single-phase solid solution. By employing high-temperature
    micromechanical testing and post-mortem microstructural characterization of refractory
    metal-based high-entropy nitrides, we observed the activation of an additional
    strengthening mechanism upon spinodal decomposition of the metastable phase into
    coherent cubic-phase domains exhibiting compositional modulation. This process
    propels the yield strength of a non-equimolar nitride at 1000 C to a staggering
    6.9 GPa, that is 43% higher than the most robust equimolar nitride. '
