The crystal structure of YAl3C3 was determined by X-ray diffraction and ab initio calculations to be a hexagonal space group P6 3 \/mmc. The lattice parameters are a=b=3.424\u00c5, c=17.291\u00c5, and the atomic positions are Y at 2a (0, 0, 0), Al1 at 2d (1\/3, 2\/3, 3\/4), Al2 at 4f (1\/3, 2\/3, 0.138), C1 at 2c (1\/3, 2\/3, 1\/4), and C2 at 4f (1\/3, 2\/3, 0.6045). The reaction synthesis path for YAl 3 C 3 was presented. Microstructure observations revealed that YAl3C3 ceramic had plate-like grain morphology. The elastic, mechanical and thermal properties of YAl3C3 were investigated. Most significantly of all, the Young\u2019s modulus of YAl3C3 could retain 276GPa (85% of that at room temperature) at 1500\u00b0C, suggesting that YAl3C3 is a promising lightweight high temperature structural material.\u00a0<\/p>\n\n\n\n<p><strong>Keyword \/\u00a0\u5173\u952e\u8bcd<\/strong><\/p>\n\n\n\n<p>Layered carbide;YAl3C3;Crystal structure;Mechanical properties;High temperature stiffness<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"799\" src=\"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2023\/11\/4-1024x799.jpg\" alt=\"\" class=\"wp-image-528\" srcset=\"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2023\/11\/4-1024x799.jpg 1024w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2023\/11\/4-300x234.jpg 300w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2023\/11\/4-768x599.jpg 768w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2023\/11\/4-1536x1199.jpg 1536w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2023\/11\/4-2048x1598.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"featured_media":528,"template":"","acf":[],"_links":{"self":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/paper\/527"}],"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\/528"}],"wp:attachment":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/media?parent=527"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
