These alloys comprised a body-centered cubic (BCC) and face-centered cubic (FCC) dual phase with a density of approximately 4.5 g\/cm3. However, the fraction of the BCC phase and morphology of the FCC phase can be controlled by incorporating other elements. The results of compression tests indicated that these Al-Ti-Cr-Mn-V alloys exhibited a prominent compression strength (~1940 MPa) and ductility (~30%). Moreover, homogenized samples maintained a high compression strength of 1900 MPa and similar ductility (30%). Due to the high specific compressive strength (0.433 GPa\u00b7g\/cm3) and excellent combination of strength and ductility, the cast lightweight Al-Ti-Cr-Mn-V MEAs are a promising alloy system for application in transportation and energy industries.<\/jats:p>","DOI":"10.3390\/e22010074","type":"journal-article","created":{"date-parts":[[2020,1,6]],"date-time":"2020-01-06T10:34:46Z","timestamp":1578306886000},"page":"74","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Development of Novel Lightweight Dual-Phase Al-Ti-Cr-Mn-V Medium-Entropy Alloys with High Strength and Ductility"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1507-3248","authenticated-orcid":false,"given":"Yu-Chin","family":"Liao","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, National Central University, Taoyuan 320, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Po-Sung","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Material Science and Engineering, National Central University, Taoyuan 320, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao-Hsiu","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Material Science and Engineering, National Central University, Taoyuan 320, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pei-Hua","family":"Tsai","sequence":"additional","affiliation":[{"name":"Institute of Material Science and Engineering, National Central University, Taoyuan 320, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason","family":"Jang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, National Central University, Taoyuan 320, Taiwan"},{"name":"Institute of Material Science and Engineering, National Central University, Taoyuan 320, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ker-Chang","family":"Hsieh","sequence":"additional","affiliation":[{"name":"Department of Materials and Optoelectronic Science, National Sun Yat-Sen University, Kaohsiung 804, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6519-3614","authenticated-orcid":false,"given":"Chih-Yen","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Materials and Optoelectronic Science, National Sun Yat-Sen University, Kaohsiung 804, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping-Hung","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Materials and Optoelectronic Science, National Sun Yat-Sen University, Kaohsiung 804, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Materials and Optoelectronic Science, National Sun Yat-Sen University, Kaohsiung 804, Taiwan"},{"name":"Institute for Advanced Study, Department of Materials Science &amp; Engineering, City University of Hong Kong, Kowloon, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsin-Jay","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Chiao Tung University, Hsinchu 300, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Chieh","family":"Lo","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Chiao Tung University, Hsinchu 300, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang-Wei","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Chung Yuan Christian University, Taoyuan 320, Taiwan"},{"name":"R&amp;D Center for Membrane Technology, Chung Yuan Christian University, Taoyuan 320, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I-Yu","family":"Tsao","sequence":"additional","affiliation":[{"name":"Institute of Material Science and Engineering, National Central University, Taoyuan 320, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"213","DOI":"10.1016\/j.msea.2003.10.257","article-title":"Microstructural development in equiatomic multicomponent alloys","volume":"375\u2013377","author":"Cantor","year":"2004","journal-title":"Mater.
