The process of additively manufacturing SiC green body, debinding and sintering has systematically studied. Meanwhile, the atomic structure of SiC and YAM was characterized, and the mechanical properties of sintered SiC ceramics were measured. The HRTEM results revealed the crystallographic orientation relationships between YAM and SiC as (0 4 0) YAM \/\/ (1 0 1- 1) SiC and [1 0 2] YAM \/\/ [1 2\u00af 1 0] SiC for the first time. The density, Vickers hardness and three-point bending strength of the sintered SiC samples are 3.11\u2009g\/cm<sup>3<\/sup>, 19.35\u2009\u00b1\u20090.28\u2009GPa and 225\u2009\u00b1\u200927\u2009MPa, respectively. Thus, PEP combined with the one-step sintering method provides a new strategy for complex-shaped SiC ceramics with high density and mechanical properties.\u00a0<\/p>\n\n\n\n<p><strong>Keyword \/\u00a0\u5173\u952e\u8bcd<\/strong><\/p>\n\n\n\n<p>Powder extrusion printing (PEP);Additive manufacturing (AM);SiC ceramics;Y;4;Al;2;O;9;(YAM);One-step sintering<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"967\" src=\"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/04\/5-1024x967.jpg\" alt=\"\" class=\"wp-image-700\" srcset=\"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/04\/5-1024x967.jpg 1024w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/04\/5-300x283.jpg 300w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/04\/5-768x725.jpg 768w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/04\/5-1536x1450.jpg 1536w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/04\/5-2048x1934.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"featured_media":700,"template":"","acf":[],"_links":{"self":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/paper\/699"}],"collection":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/paper"}],"about":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/types\/paper"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/media\/700"}],"wp:attachment":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/media?parent=699"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
