The quasi-harmonic temperature-dependent elastic constants are calculated and compared with existing experiments and with the quasi-static approximation. We find that the quasi-harmonic approximation allows for a much better interpretation of the experimental data, confirming the trend found previously in other metals. Using the Voigt\u2013Reuss\u2013Hill average, we predict the compressional and shear sound velocities of polycrystalline molybdenum as a function of pressure for several temperatures, which might be accessible in experiments.<\/jats:p>","DOI":"10.1063\/5.0212162","type":"journal-article","created":{"date-parts":[[2024,6,24]],"date-time":"2024-06-24T12:25:19Z","timestamp":1719231919000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":15,"title":["<i>Ab initio<\/i> quasi-harmonic thermoelasticity of molybdenum at high temperature and pressure"],"prefix":"10.1063","volume":"160","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3084-8649","authenticated-orcid":false,"given":"X.","family":"Gong","sequence":"first","affiliation":[{"name":"International School for Advanced Studies (SISSA) 1 , Via Bonomea 265, 34136 Trieste,","place":["Italy"]},{"name":"IOM - CNR 2 , Via Bonomea 265, 34136 Trieste,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1186-5133","authenticated-orcid":false,"given":"A.","family":"Dal Corso","sequence":"additional","affiliation":[{"name":"International School for Advanced Studies (SISSA) 1 , Via Bonomea 265, 34136 Trieste,","place":["Italy"]},{"name":"IOM - CNR 2 , Via Bonomea 265, 34136 Trieste,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2024,6,24]]},"reference":[{"key":"2024121311212736900_c1","doi-asserted-by":"publisher","first-page":"208","DOI":"10.1063\/1.324325","volume":"49","year":"1978","journal-title":"J.\u00a0Appl.
