The results demonstrated that during the sintering process, TiB2 located on the boundaries between different B4C grains could inhibit the grain growth which improved the mass transport mechanism and sintering driving force. A semi-coherent interface between B4C and SiC was found, which is supposed to help to reduce the interface energy and obtain good mechanical properties of the B4C\/TiB2 ceramic composite. On sample cooling from sintering temperature to room temperature, the residual tensile stress fields formed at the TiB2 interfaces owning to the thermo-elastico properties mismatched, which might have contributed to increase the ability of the sample to resist crack propagation. The results showed that the relative density, Vickers hardness, and fracture toughness of the composite with 20 wt.% submicron and 10 wt.% nano-TiB2 were significantly improved, which were 98.6%, 30.2 GPa, and 5.47 MPa\u00b7m1\/2, respectively.<\/jats:p>","DOI":"10.3390\/ma14185227","type":"journal-article","created":{"date-parts":[[2021,9,12]],"date-time":"2021-09-12T21:45:57Z","timestamp":1631483157000},"page":"5227","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Effects of TiB2 Particles on the Microstructure Evolution and Mechanical Properties of B4C\/TiB2 Ceramic Composite"],"prefix":"10.3390","volume":"14","author":[{"given":"Haiyan","family":"Niu","sequence":"first","affiliation":[{"name":"Science and Technology on Complex and System Simulation Laboratory, Beijing 100072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Zhu","sequence":"additional","affiliation":[{"name":"Beijing Institute of Aerospace Control Devices, Beijing 100039, China"},{"name":"School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ning","family":"You","sequence":"additional","affiliation":[{"name":"Science and Technology on Complex and System Simulation Laboratory, Beijing 100072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3899-9772","authenticated-orcid":false,"given":"Yangwei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China"},{"name":"National Key Laboratory of Science and Technology on Materials under Shock and Impact, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huanwu","family":"Cheng","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China"},{"name":"National Key Laboratory of Science and Technology on Materials under Shock and Impact, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dujun","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengying","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiamin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1016\/0955-2219(90)90048-K","article-title":"Boron Carbide\u2014A Comprehensive Review","volume":"6","author":"Thevent","year":"1990","journal-title":"J.
