外文摘要：The manufacturing of heterogeneous high-temperature material components is challenging for use in practical applications.Three-dimensional(3D)printing provides solutions to programmable constructing ceramic architectures.However,the development of heterogeneous ceramics is limited by low flexibil-ity of heterogeneity,geometrical complexity,structural resolution,manufacturing efficiency,and mate-rial diversity.In this study,we demonstrated flexible and rapid approaches for fabricating complicated and precise heterogeneous ceramics by shape-changing(4D)or shape-keeping(3D)additive-subtractive manufacturing(ASM)methods.The shape-changing strategy for heterogeneous ceramics was achieved by global ceramization of heterogeneous precursors,while the shape-keeping strategy for heterogeneous ceramics was achieved by local receramization of homogeneous ceramics.Finite element analysis(FEA)simulations of the influence of the thermal shrinkage dominant in the shape-changing strategy on the shape deformation of heterogeneous ceramics could be valuable predictions of the experimental results.The 3D/4D ASM methods are generic for high-temperature materials and extendable to metallic and dia-mond materials.
