A few iso-<span>(Delta G^{M})</span> couples were assembled with FCC Fe-Ni-Cu alloys at 1000 °C. To enable the selection of the terminal alloys for iso-<span>(Delta G^{M})</span> couples, iso-<span>(Delta G^{M})</span> lines were constructed from the data on the thermodynamic activities of the constituent elements in FCC Fe-Ni-Cu alloys at 1000 °C. A few couples were also studied whose composition vectors were at about 90°, less than 90° and greater than 90° to one of the iso-<span>(Delta G^{M})</span> couples. A strategy is also proposed and utilized to construct a near iso-Gibbs free energy (iso-<span>(G^{soln})</span>) couple. All but one iso-<span>(Delta G^{M})</span> couples and also, the iso-<span>(G^{soln})</span> couple were characterized by almost linear diffusion paths. All the iso-<span>(Delta G^{M})</span> couples presented very low diffusion depths characterized in terms of effective penetration depth (<span>(overline{x})</span>), with the iso-<span>(G^{soln})</span> couple exhibiting the lowest values of <span>(overline{x})</span>. This experimental work clearly reveals the definite role played by the difference in Gibbs free energies of terminal alloys in dictating the diffusion paths and the relative diffusion depths in the diffusion couples.</p></div>","PeriodicalId":657,"journal":{"name":"Journal of Phase Equilibria and Diffusion","volume":"45 2","pages":"175 - 184"},"PeriodicalIF":1.5,"publicationDate":"2024-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140199233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is one of the most helpful implements for the construction of the liquidus surface of ternary phase diagrams. In its original form, it allows to find the direction of falling or increasing temperature along the monovariant reaction lines forming the boundaries of the primary crystallization fields. The theorem is valid for systems with any number of phases; however, its geometrical construction rule is only defined for the case of stoichiometric phases and it is not clear how to apply the theorem in the case of phases with extended homogeneity ranges. Some examples from a ternary, transition-metal-based system containing phases with large homogeneity ranges are presented, and the usefulness and limits of applicability of the theorem are discussed.</p></div>","PeriodicalId":657,"journal":{"name":"Journal of Phase Equilibria and Diffusion","volume":"45 3","pages":"489 - 501"},"PeriodicalIF":1.5,"publicationDate":"2024-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11669-024-01097-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140077028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considered works allow us to characterize them as valuable environmentally friendly functional materials with great potential for practical application. The main approaches which have been used in these works to enhance functional properties, as well as to improve the application capabilities of this class of substances have been analyzed. The importance of further systematic investigations on their design based on the “composition-structure-property” relationship has been noted. In the present review, special attention is paid to the analysis of works on phase equilibria in the corresponding systems since the information accumulated in phase diagrams is extremely important for optimizing the properties of compounds through targeted variation of composition and structure. Available data on the phase equilibria and thermodynamic properties of ternary and quaternary systems forming Cu/Ag argyrodite compounds and solid solutions based on them are presented and analyzed. It has been shown that anionic and Cu ↔ Ag substitutions in compounds lead to a strong decrease in their polymorphic phase transition temperatures and an expansion of the temperature-composition ranges of the existence of high-temperature ion-conducting phases up to room temperature and below. The possibility of replacing part of the chalcogen atoms in the compounds with halogens, and the Cu(Ag) atoms with elements of the zinc subgroup, which expands the range of argyrodite phases is also shown. The significance of expanding studies of phase equilibria and thermodynamic properties of these systems, especially five-component and more complex systems possessing a big possibility of the formation of high-entropy argyrodite phases, which have thermodynamic stability in a wide temperature-composition range and better applied characteristics has also been specified.</p></div>","PeriodicalId":657,"journal":{"name":"Journal of Phase Equilibria and Diffusion","volume":"45 3","pages":"228 - 255"},"PeriodicalIF":1.5,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140075118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the Si content in the bath was higher than 2.5 wt.%, a new intermetallic compound, Al₇(Fe, Cr)₂Si, appeared at the interface, and the thickness of the metal compound layer decreased continuously upon increasing the silicon content in the melt pool. When the hot-dipped sample was annealed in vacuum at 900 °C for 3 h, the brittle (Fe, Cr, Ni)₂Al₅ phase was transformed into a ductile (Fe, Cr, Ni)Al phase. As low-oxygen pressure oxidation progressed, FeAl/Al₂O₃ gradient coatings were formed on the surface layer.
