In order to find a structural explanation for the different dynamic behavior, we have studied the short-range structure of stable and undercooled Ti\n                    <jats:sub>75<\/jats:sub>\n                    Ni\n                    <jats:sub>25<\/jats:sub>\n                    melts. The melts were containerlessly processed under high-purity conditions by application of the electrostatic levitation technique. Partial structure factors of the liquid alloys have been determined by a combination of neutron diffraction (with isotopic substitution) and synchrotron x-ray diffraction. The studies reveal that Ti\n                    <jats:sub>75<\/jats:sub>\n                    Ni\n                    <jats:sub>25<\/jats:sub>\n                    melts are characterized by a chemical short-range order, where heterogeneous Ti-Ni nearest neighbors are preferentially formed. This chemical short-range order, however, is less pronounced than the chemical short-range order reported for melts of Zr\n                    <jats:sub>64<\/jats:sub>\n                    Ni\n                    <jats:sub>36<\/jats:sub>\n                    and Ni\n                    <jats:sub>66.7<\/jats:sub>\n                    B\n                    <jats:sub>33.3<\/jats:sub>\n                    . The less pronounced chemical short-range order may account for the faster atomic dynamics reported for liquid Ti\n                    <jats:sub>75<\/jats:sub>\n                    Ni\n                    <jats:sub>25<\/jats:sub>\n                    . For a further analysis of the structure-dynamics relationship the experimentally determined partial structure factors were used as an input for calculations in the framework of the mode coupling theory (MCT) of the glass transition. These reveal that the Ni self-diffusion is only slightly faster than the Ti self-diffusion with a ratio of the self-diffusion coefficients\n                    <jats:italic>D<\/jats:italic>\n                    <jats:sub>Ni<\/jats:sub>\n                    \/\n                    <jats:italic>D<\/jats:italic>\n                    <jats:sub>Ti<\/jats:sub>\n                    <jats:italic>\u2248<\/jats:italic>\n                    1.2. Moreover, the Onsager coefficients calculated by MCT are in good agreement with those estimated by use of Darken\u2019s equation indicating that cross-correlation effects are negligible when describing the interdiffusion in liquid Ti\n                    <jats:sub>75<\/jats:sub>\n                    Ni\n                    <jats:sub>25<\/jats:sub>\n                    .\n                  <\/jats:p>","DOI":"10.1088\/1361-648x\/ae4e77","type":"journal-article","created":{"date-parts":[[2026,3,6]],"date-time":"2026-03-06T22:53:34Z","timestamp":1772837614000},"page":"115402","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Short-range order and atomic dynamics of Ti\n                    <sub>75<\/sub>\n                    Ni\n                    <sub>25<\/sub>\n                    melts"],"prefix":"10.1088","volume":"38","author":[{"given":"Johanna","family":"Wilden","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2457-7427","authenticated-orcid":true,"given":"Dirk","family":"Holland-Moritz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5281-2957","authenticated-orcid":true,"given":"Fan","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9912-5764","authenticated-orcid":true,"given":"Nico","family":"Neuber","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1696-271X","authenticated-orcid":true,"given":"Ralf","family":"Busch","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1261-9295","authenticated-orcid":true,"given":"Thomas","family":"Voigtmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas C","family":"Hansen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Buslaps","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0604-5467","authenticated-orcid":true,"given":"Andreas","family":"Meyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2026,3,18]]},"reference":[{"key":"cmae4e77bib1","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-030-89784-0_7","type":"book","article-title":"Theory of nucleation and glass formation","author":"Kelton","year":"2022"},{"key":"cmae4e77bib2","doi-asserted-by":"publisher","first-page":"196","DOI":"10.3390\/met4020196","type":"journal-article","volume":"4","author":"Herlach","year":"2014","journal-title":"Metals"},{"key":"cmae4e77bib3","doi-asserted-by":"publisher","first-page":"941","DOI":"10.1016\/j.actamat.2008.10.020","type":"journal-article","volume":"57","author":"Asta","year":"2009","journal-title":"Acta Mater."},{"key":"cmae4e77bib4","author":"Kurz","year":"1992","edition":"3rd edn","type":"book"},{"key":"cmae4e77bib5","volume":"vol 143","author":"G\u00f6tze","year":"2008","type":"book"},{"key":"cmae4e77bib6","doi-asserted-by":"publisher","first-page":"241","DOI":"10.1088\/0034-4885\/55\/3\/001","type":"journal-article","volume":"55","author":"G\u00f6tze","year":"1992","journal-title":"Rep.
