In this study, a novel technology, Powder Extrusion Printing (PEP) combined with in-situ reaction, was successfully employed to prepare the high performance of TiC matrix composite cutting tools using Ti<sub>3<\/sub>AlC<sub>2<\/sub>&nbsp;and Ni as raw materials. The formation of TiC and NiAl was observed in the sintered sample. The crystallographic orientation relationships in TiC-Ti<sub>2<\/sub>AlC-NiAl interfaces were also determined, as follows: TiC [11\u22122]\u2225Ti<sub>2<\/sub>AlC [1\u2212100]\u2225NiAl [-110], TiC (111)\u2225Ti<sub>2<\/sub>AlC (000\u22122)\u2225NiAl (110). As the load increases from 0.3\u202fkg to 10\u202fkg, the Vickers hardness (HV) gradually decreases from 12.51\u202f\u00b1\u202f0.40\u202fGPa to 11.12\u202f\u00b1\u202f0.10\u202fGPa. The three-point bending strength, fracture toughness (K<sub>IC<\/sub>) and compressive strength of the sintered samples were 528.30\u202f\u00b1\u202f63\u202fMPa, 6.31\u202f\u00b1\u202f0.17\u202fMPa\u00b7m<sup>1\/2<\/sup>&nbsp;and 1211\u202f\u00b1\u202f165\u202fMPa, respectively. Thus, this technology exhibits excellent application potential in the fabrication of ceramic-based composites with complex shapes.<\/p>\n\n\n\n<p><strong>Keywords \/&nbsp;\u5173\u952e\u8bcd<\/strong><\/p>\n\n\n\n<p>Additive manufacturing; Powder extrusion printing (PEP); TiC matrix composites; In-situ reaction<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"678\" height=\"703\" src=\"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2025\/08\/1-s2.0-S0925838825042240-gr3.jpg\" alt=\"\" class=\"wp-image-780\" srcset=\"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2025\/08\/1-s2.0-S0925838825042240-gr3.jpg 678w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2025\/08\/1-s2.0-S0925838825042240-gr3-289x300.jpg 289w\" sizes=\"(max-width: 678px) 100vw, 678px\" \/><\/figure><\/div>","protected":false},"featured_media":783,"template":"","acf":[],"_links":{"self":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/paper\/779"}],"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\/783"}],"wp:attachment":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/media?parent=779"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
