In this research, Mössbauer spectroscopy, complemented with transmission electron microscopy, x-ray diffraction, hardness measurements, and optical microscopy techniques, was used to investigate the phase transformation process of solution-treated and 480 °C-aged Maraging-300 steel specimens. The results indicated that the precipitation of intermetallic compounds starts at the early stages of aging and that these precipitates are Fe-free, which are responsible for improving mechanical properties. Atomic mobility is discussed, and precipitate formation is evidenced.

This study delves into the complexities of stacking fault energy (SFE) in Fe-Mn binary system using the concept of a 3rd generation Calphad database which is suitable for thermodynamic calculations at low temperatures. Releases of 3rd generation Calphad descriptions for unary Fe and Mn in recent years, motivated the authors to address the SFE using a re-assessment of thermodynamic description for the Fe-Mn binary system. The obtained SFE values are calculated thermodynamically and discussed in relation to the material's behavior and properties. SFE values are computed through a revised thermodynamic method of Olson-Cohen, and the relationship between this quantity and properties of material is discussed. This research not only serves to augment our understanding of SFE and related physical phenomena but also identifies regions where thermodynamic databases can be refined. The effectiveness of ICME and Calphad methodologies is demonstrated, contributing to the advancement of materials design and, consequently, the enhancement of performance and reliability in low-temperature applications.</div>","PeriodicalId":657,"journal":{"name":"Journal of Phase Equilibria and Diffusion","volume":"46 2","pages":"221 - 238"},"PeriodicalIF":1.5,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117687","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}

Five La-Co binary intermetallic compounds (LaCo13, LaCo5, β-La2Co7, La2Co3, La2Co1.7) and five Co-Ti binary intermetallic compounds (Co3Ti, Co2Ti(h), Co2Ti(c), CoTi and CoTi2) were observed, while the intermetallic compound La5Co19 was not found. Two ternary intermetallic compounds La2Co17-xTix (0.5 ≤ x ≤ 1.3) with a Th2Zn17-type structure and LaCo12-xTix (1.5 ≤ x ≤ 1.7) with a ThMn12-type structure were detected at 873 K, while the ternary intermetallic compound La2Co17-xTix (0.5 ≤ x ≤ 1.3) is only existent at 1073 K. Furthermore, the measured phase compositions show that the solubility of the third element in the La-Co and Co-Ti binary intermetallic compounds is negligible (less than 1 at.%).

The computed values of excess Gibbs energy of mixing, enthalpy of mixing, and activity of components in the binary liquid alloys are in good agreement with the experimental data. The surface tension and viscosity of the ternary alloys are highly influenced by the fluctuations in the bulk amount of Cu.
