This paper studied their microstructure and compression properties. The results show that all the TaNbVTiAlx RHEAs exhibited a single BCC solid solution microstructure with no elemental segregation. The P\/M TaNbVTiAlx RHEAs showed excellent room-temperature specific strength (207.11 MPa*cm3\/g) and high-temperature specific strength (88.37 MPa*cm3\/g at 900 \u00b0C and 16.03 MPa*cm3\/g at 1200 \u00b0C), with reasonable plasticity, suggesting that these RHEAs have potential to be applied at temperatures &gt;1200 \u00b0C. The reasons for the excellent mechanical properties of P\/M TaNbVTiAl0.2 RHEA were the uniform microstructure and solid solution strengthening effect.<\/jats:p>","DOI":"10.3390\/e22030282","type":"journal-article","created":{"date-parts":[[2020,3,2]],"date-time":"2020-03-02T04:16:16Z","timestamp":1583122576000},"page":"282","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Microstructure and Mechanical Properties of TaNbVTiAlx Refractory High-Entropy Alloys"],"prefix":"10.3390","volume":"22","author":[{"given":"Li","family":"Xiang","sequence":"first","affiliation":[{"name":"State Key Lab of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1965-9230","authenticated-orcid":false,"given":"Wenmin","family":"Guo","sequence":"additional","affiliation":[{"name":"State Key Lab of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Lab of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ao","family":"Fu","sequence":"additional","affiliation":[{"name":"State Key Lab of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianbo","family":"Li","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Chongqing University, Chongqing 400044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qihong","family":"Fang","sequence":"additional","affiliation":[{"name":"College of Mechanical and Vehicle Engineering, Hunan University, Changsha 410082, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Lab of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1016\/j.jallcom.2018.05.067","article-title":"A review on fundamental of high entropy alloys with promising high\u2013temperature properties","volume":"760","author":"Chen","year":"2018","journal-title":"J.
