The study of the solidified microstructure, thermodynamics and phase equilibria in the ternary Cu\u2013Zr\u2013Y system is expected to provide new insight into designing an HSHC copper alloy. In this work, the solidified and equilibrium microstructure and phase transition temperatures in the Cu\u2013Zr\u2013Y ternary system were studied by X-ray diffraction (XRD), electron probe microanalysis (EPMA) and differential scanning calorimeter (DSC). The isothermal section at 973 K was experimentally constructed. No ternary compound was found, while the Cu6Y, Cu4Y, Cu7Y2, Cu5Zr, Cu51Zr14 and CuZr phases substantially extended into the ternary system. According to the experimental phase diagram data from the present work and the literature, the Cu\u2013Zr\u2013Y ternary system was assessed using the CALPHAD (CALculation of PHAse diagrams) method. The isothermal sections, vertical section and liquidus projection calculated by the present thermodynamic description agree well with the experimental results. This study not only establishes a thermodynamic description of the Cu\u2013Zr\u2013Y system, but also contributes to the design of a copper alloy with the required microstructure.<\/jats:p>","DOI":"10.3390\/ma16052063","type":"journal-article","created":{"date-parts":[[2023,3,3]],"date-time":"2023-03-03T01:43:00Z","timestamp":1677807780000},"page":"2063","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Phase Equilibria, Thermodynamics and Solidified Microstructure in the Copper\u2013Zirconium\u2013Yttrium System"],"prefix":"10.3390","volume":"16","author":[{"given":"Fengting","family":"Jing","sequence":"first","affiliation":[{"name":"State Key Laboratory of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuling","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4187-3989","authenticated-orcid":false,"given":"Yong","family":"Du","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chenying","family":"Shi","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Powder Metallurgy, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Biao","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Anhui University of Science and Technology, Huainan 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiancong","family":"He","sequence":"additional","affiliation":[{"name":"School of Material Science and Engineering, Nanjing Institute of Technology, Nanjing 211167, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"394","DOI":"10.1080\/09506608.2020.1821485","article-title":"Copper-based alloys for structural high-heat-flux applications: A review of development, properties, and performance of Cu-rich Cu-Cr-Nb alloys","volume":"66","author":"Minneci","year":"2021","journal-title":"Int.
