The feasibility of the Zr deoxidation instead of Al deoxidation was confirmed by the thermodynamic analysis of the deoxidation of various elements. The experimental results indicate that the average diameters of the inclusions in Al-Steel and Zr-Steel were 2.45 \u03bcm and 1.65 \u03bcm, respectively. The Al-Steel and Zr-Steel contained 22.38% and 68.77% inclusions per unit area, respectively, and the fraction of inclusions in the Al-Steel and Zr-Steel with diameters less than 2 \u03bcm was about 73.46% and 89.63%, respectively, indicating that the Zr deoxidation process could effectively refine inclusions and promote dispersion. The average diameters of austenite grain for the Al-Steel and Zr-Steel were about 9.1 \u03bcm and 8 \u03bcm, respectively. The fine particles in Zr-Steel could pin the austenite grain boundaries and clearly refine the grains. The average grain size of tempered martensite was 8.2 \u03bcm and 3.8 \u03bcm, respectively. The yield strength of the Al-Steel and Zr-Steel was 922 MPa and 939 MPa, respectively; the impact energy was 60 \u00b1 6 J and 132 \u00b1 6 J, respectively. Moreover, the fracture time of the NACE-A was from 28 h (Al-Steel) to 720 h (Zr-Steel) without fracture. The experimental steel deoxidized by Zr achieved a simultaneous improvement in strength, toughness and sulfide stress corrosion resistance, and the effect of inclusions on the fracture of the sulfide stress corrosion resistant high-strength steel can be explained by the Griffith theory.<\/jats:p>","DOI":"10.3390\/ma15134544","type":"journal-article","created":{"date-parts":[[2022,6,29]],"date-time":"2022-06-29T01:48:38Z","timestamp":1656467318000},"page":"4544","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effect of Oxide Metallurgy on Inclusions in 125 ksi Grade OCTG Steel with Sulfide Stress Corrosion Resistance"],"prefix":"10.3390","volume":"15","author":[{"given":"Si","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Electromagnetic Processing of Materials, Northeastern University, Shenyang 110819, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanmei","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Rolling and Automation, Northeastern University, Shenyang 110819, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Electromagnetic Processing of Materials, Northeastern University, Shenyang 110819, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuxian","family":"Zhu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Rolling and Automation, Northeastern University, Shenyang 110819, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulong","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Electromagnetic Processing of Materials, Northeastern University, Shenyang 110819, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bang","family":"Xiao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Electromagnetic Processing of Materials, Northeastern University, Shenyang 110819, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104418","DOI":"10.1016\/j.jngse.2022.104418","article-title":"The influence of H2S on hydrogen absorption and sulfide stress cracking resistance of high strength low alloy carbon steel C110","volume":"99","author":"Liu","year":"2022","journal-title":"J.
