Thermodynamic calculations revealed that CO pressure affected the formation of ZrB2 at temperatures from 814 \u00b0C to 1100 \u00b0C. The experimental results showed that the ZrB2 grain size was &lt;5 \u00b5m and that the grains were uniformly distributed within the B4C ceramics. With an increase in ZrO2 content, the Vickers hardness and flexural strength of the B4C ceramics first increased and then decreased, while the fracture toughness continuously increased. When the content of ZrO2 was 15 wt%, the Vickers hardness, fracture toughness and flexural strength of B4C ceramics were 35.5 \u00b1 0.63 GPa, 3.6 \u00b1 0.24 MPa\u00b7m1\/2 and 403 \u00b1 10 MPa, respectively. These results suggest that ZrB2 inhibits B4C grain growth, eliminates crack tip stress, and provides fine grain to strengthen and toughen B4C ceramics.<\/jats:p>","DOI":"10.3390\/ma15227961","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T21:33:02Z","timestamp":1668115982000},"page":"7961","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["In Situ ZrB2 Formation in B4C Ceramics and Its Strengthening Mechanism on Mechanical Properties"],"prefix":"10.3390","volume":"15","author":[{"given":"Wankai","family":"Yao","sequence":"first","affiliation":[{"name":"The State Key Laboratory of Refractories and Metallurgy, Wuhan University of Science and Technology, Wuhan 430081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junbing","family":"Yan","sequence":"additional","affiliation":[{"name":"Wuhan Xinxin Semiconductor Manufacturing Co., Ltd., Wuhan 430223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3909-6316","authenticated-orcid":false,"given":"Xiangcheng","family":"Li","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Refractories and Metallurgy, Wuhan University of Science and Technology, Wuhan 430081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pingan","family":"Chen","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Refractories and Metallurgy, Wuhan University of Science and Technology, Wuhan 430081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingli","family":"Zhu","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Refractories and Metallurgy, Wuhan University of Science and Technology, Wuhan 430081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boquan","family":"Zhu","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Refractories and Metallurgy, Wuhan University of Science and Technology, Wuhan 430081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sha, W., Liu, Y., Zhou, Y., Huang, Y., and Huang, Z.
