摘要	Highly densified Al4SiC4 ceramics with a relative density of 96.1% were prepared by pressureless sintering using 2 wt% Y2O3 as additives. The densification mechanism, phase composition, microstructures and mechanical properties of Al4SiC4 ceramics were investigated. Y2O3 in-situ reacted with the oxygen impurities in Al4SiC4 powder to form a yttrium aluminate liquid phase during sintering, which promoted the densification and anisotropic grain growth. The final Al4SiC4 ceramics were composed of equiaxed grains and columnar grains, and presented a bimodal grain distribution. The mechanical properties of the pressureless sintered Al4SiC4 ceramics were better than those reported for hot pressed Al4SiC4, including a flexural strength of 369 ± 24 MPa, fracture toughness of 4.8 ± 0.1 MPa m1/2 and Vickers hardness of 11.3 ± 0.2 GPa. Pressureless sintering of Al4SiC4 ceramics is of great significance for the development and practical application of Al4SiC4 ceramic parts, especially with big size and complex shape. © 2023 Elsevier Ltd
