Spherical L12-structured precipitates with mean particle radius of 10Å form after aging. Slow volumetric coarsening rates of 5.73 × 10<sup>−30</sup> (at 375 °C), 2.51x10<sup>−29</sup> (at 400 °C), and 5.86 × 10<sup>−28</sup> (at 450 °C) m<sup>3</sup>/hr are measured for the L12-structured Al<sub>3</sub>(Zr<sub>0.67</sub>Nb<sub>0.33</sub>) precipitates in the melt spun ribbon. From a modified LSW equation for volumetric coarsening, an interfacial energy of 0.013 J/m<sup>2</sup> is calculated. This value agrees well with the reported values for a coherent interface. Most particle size distributions (PSDs) of precipitates under investigation also fit quite well to that predicted by MLSW theory. The above points, therefore, prove that Nb is really a useful candidate for addition into an Al-Cr-Zr high temperature Al alloy.</p></div>","PeriodicalId":101150,"journal":{"name":"Scripta Metallurgica et Materialia","volume":"33 12","pages":"Pages 1999-2005"},"PeriodicalIF":0.0,"publicationDate":"1995-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0956-716X(95)00475-B","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79443810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
