Some new body-centered-cubic random multicomponent "high entropy alloys (HEAs)" based on refractory elements (Cr-Mo-Nb-Ta-V-W-Hf-Ti-Zr) possess exceptional strengths at high temperatures but the physical origins of this outstanding behavior are not known. Here, by using a recent mechanistic theory, we have computed the high-temperature (T=1300K) yield strength based on solute strengthening of over 10 million alloys within the whole Al-Cr-Mo-Nb-Ta-V-W-Hf-Ti-Zr alloy family. Also the yield strength/density has been computed. This database enables the efficient search of new alloys with exceptional high-temperature strength. text/markdown text/plain application/octet-stream application/zip application/zip https://doi.org/10.24435/materialscloud:fs-27 oai:materialscloud.org:826 mcid:2021.65 eng Materials Cloud https://arxiv.org/abs/2008.11671 https://doi.org/10.1016/j.actamat.2019.10.015 https://archive.materialscloud.org/communities/mcarchive https://doi.org/10.24435/materialscloud:21-py info:eu-repo/semantics/openAccess Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode High entropy alloys Solute strengthening High temperature strength ERC EPFL Prediction of yield strength in refractory body-centered-cubic High Entropy Alloys info:eu-repo/semantics/other
