Temporal evolutions of the morphology, size, and volume fraction of the nanoscaled L12-(Ni,Co)3Ti precipitates at 800 \u00b0C with various aging time were quantitatively evaluated. The ultimate tensile strength can be greatly improved to ~1200 MPa, accompanied with a tensile elongation of ~20% after precipitation. The temporal exponents for the average size and number density of precipitates reasonably conform the predictions by the PV model. A composite model was proposed to describe the plastic strain of the current HEA. As a consequence, the tensile strength and tensile elongation are well predicted, which is in accord with the experimental results. The present experiment provides a theoretical reference for the strengthening of partially recrystallized single-phase HEAs in the future.<\/jats:p>","DOI":"10.3390\/e21040389","type":"journal-article","created":{"date-parts":[[2019,4,12]],"date-time":"2019-04-12T03:46:37Z","timestamp":1555040797000},"page":"389","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Prediction of Strength and Ductility in Partially Recrystallized CoCrFeNiTi0.2 High-Entropy Alloy"],"prefix":"10.3390","volume":"21","author":[{"given":"Hanwen","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Materials Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Peizhi","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Interface Science and Engineering in Advanced Materials, Ministry of Education, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Jinxiong","family":"Hou","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Junwei","family":"Qiao","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, China"},{"name":"Key Laboratory of Interface Science and Engineering in Advanced Materials, Ministry of Education, Taiyuan University of Technology, Taiyuan 030024, China"}]},{"given":"Yucheng","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Interface Science and Engineering in Advanced Materials, Ministry of Education, Taiyuan University of Technology, Taiyuan 030024, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1153","DOI":"10.1126\/science.1254581","article-title":"A fracture-resistant high-entropy alloy for cryogenic applications","volume":"345","author":"Gludovatz","year":"2014","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1038\/nature17981","article-title":"Metastable high-entropy dual-phase alloys overcome the strength-ductility trade-off","volume":"534","author":"Li","year":"2016","journal-title":"Nature"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"14390","DOI":"10.1038\/ncomms14390","article-title":"Dislocation mechanisms and 3D twin architectures generate exceptional strength-ductility-toughness combination in CrCoNi medium-entropy alloy","volume":"8","author":"Zhang","year":"2017","journal-title":"Nat.
