Their microstructures and compressive mechanical behavior at room temperature were investigated. It has been found that a single solid-solution phase with a body-centered cubic (BCC) crystal structure forms in these alloys. Among these alloys, Al0.5NbTiMoV reaches the highest yield strength (1,625 MPa), which should be attributed to the considerable solid-solution strengthening behavior. Furthermore, serration and crackling noises near the yielding point was observed in the NbTiMoV alloy, which represents the first such reported phenomenon at room temperature in HEAs.<\/jats:p>","DOI":"10.3390\/e16020870","type":"journal-article","created":{"date-parts":[[2014,2,13]],"date-time":"2014-02-13T11:20:15Z","timestamp":1392290415000},"page":"870-884","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":180,"title":["Microstructures and Crackling Noise of AlxNbTiMoV High Entropy Alloys"],"prefix":"10.3390","volume":"16","author":[{"given":"Shu","family":"Chen","sequence":"first","affiliation":[{"name":"State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Xiao","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Karin","family":"Dahmen","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Illinois at Urbana-Champaign, 1110 West Green Street, Urbana, IL 61801, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0185-3411","authenticated-orcid":false,"given":"Peter","family":"Liaw","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, The University of Tennessee, Knoxville, TN 37996, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6355-9923","authenticated-orcid":false,"given":"Yong","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, Beijing 100083, China"}]}],"member":"1968","published-online":{"date-parts":[[2014,2,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1002\/adem.200300567","article-title":"Nanostructured high-entropy alloys with multiple pr incipal elements: Novel alloy design concepts and outcomes","volume":"6","author":"Yeh","year":"2004","journal-title":"Adv.
