A series of Ti\u2013(8\u201328)Nb\u2013(0\u20133)O (at.%) alloys were prepared and solution-treated in the \u03b2-phase field. The microstructure and crystallography were characterized by X-ray diffraction (XRD), electron microscopy and reciprocal-space mapping. A 2D-XRD orientation simulation approach was applied to distinguish all 12 crystallographically equivalent \u03b1\u2033-martensitic variants originating from a single prior \u03b2 grain, enabling detailed diffraction analysis. This method further allowed quantitative evaluation of the atomic shuffle parameter\n                    <jats:italic>y<\/jats:italic>\n                    , describing the \u03b2\u2192\u03b1\u2033 transformation. The results demonstrate that Nb primarily governs \u03b1\u2033-martensite evolution. Increasing Nb stabilizes the \u03b2 phase and shifts the \u03b1\u2033 structure toward higher symmetry, as reflected by systematic changes in lattice parameters and increasing shuffle parameter\n                    <jats:italic>y<\/jats:italic>\n                    , indicating suppression of the transformation to the hexagonal \u03b1\u2032 phase. Oxygen, in contrast, modifies the transformation pathways. At lower Nb contents, it suppresses \u03c9-phase formation and promotes \u03b2\u2192\u03b1\u2033 transformation, while at higher Nb levels it inhibits long-range martensitic transformation, resulting in retained \u03b2 or competing \u03c9 phase. These effects are attributed to local lattice distortions induced by interstitial oxygen.\n                  <\/jats:p>","DOI":"10.1107\/s1600576726007739","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T15:09:28Z","timestamp":1787584168000},"page":"1570-1583","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["The effect of Nb and O on the martensitic transformation in Ti\u2013Nb\u2013O alloys"],"prefix":"10.1107","volume":"59","author":[{"given":"Kristi\u00e1n","family":"\u0160alata","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/024d6js02","id-type":"ROR","asserted-by":"publisher"}],"department":["Department of Physics of Materials"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8105-2563","authenticated-orcid":true,"given":"Dalibor","family":"Preisler","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/024d6js02","id-type":"ROR","asserted-by":"publisher"}],"department":["Department of Physics of Materials"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josef","family":"Str\u00e1sk\u00fd","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/024d6js02","id-type":"ROR","asserted-by":"publisher"}],"department":["Department of Physics of Materials"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5722-2243","authenticated-orcid":true,"given":"Ji\u0159\u00ed","family":"Kozl\u00edk","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/024d6js02","id-type":"ROR","asserted-by":"publisher"}],"department":["Department of Physics of Materials"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1835-9850","authenticated-orcid":true,"given":"Luk\u00e1\u0161","family":"Hor\u00e1k","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/024d6js02","id-type":"ROR","asserted-by":"publisher"}],"department":["Department of Condensed Matter Physics"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0370-6928","authenticated-orcid":true,"given":"V\u00e1clav","family":"Hol\u00fd","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/024d6js02","id-type":"ROR","asserted-by":"publisher"}],"department":["Department of Condensed Matter Physics"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,9,25]]},"reference":[{"key":"har5007_bb1","doi-asserted-by":"crossref","first-page":"407","DOI":"10.1016\/j.jmbbm.2012.11.014","volume":"20","author":"Abdel-Hady Gepreel","year":"2013","journal-title":"J.
