Microstructural design is a promising strategy to enhance the toughness and plasticity of structural ceramics while maintaining their inhrinsic excellent hardness, which can facilitate their applications in extreme environments.In this paper, we report the possibility of establishing a symbiotic-structure with metal atomiclayer phase-separation (MALPS) in carbide structural ceramics.The MALPS structure is not a MAX phase with long-range-order but rather a composite featuring a non-periodic cross-stacking of single metal atomic layers within the carbide matrix.The carbide ceramic samples were synthesized from raw materials comprising transition metals with different component numbers, graphite powders, and a small amount of aluminum by
