In the conventional process, heating of the reaction vessel is continued till self-initiation or self-firing of the reaction occurs. A novel deterministic reaction triggering (DRT) method has been developed for the MTR process on a 5 kg uranium ingot scale, which makes the firing definite and decreases specific energy consumption and batch duration by about 33.8% and 30–50%, respectively, without affecting the process recovery. The pre-heat time and pre-heat temperature required for initiating the external trigger were estimated using COMSOL simulations and thermodynamic evaluation of the final product temperature, respectively. The process recovery with DRT (~93%) was comparable to that of the conventional self-firing process. A well-consolidated uranium ingot with a recovery of about 93% was obtained with 100 ppm Cr and 97 ppm Ni in the scaled up (50 kg) batch by employing deterministic triggering. This DRT method is applicable and useful for similar reaction processes for augmenting process capacity and energy utilization.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1438 - 1451"},"PeriodicalIF":2.1,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11837-024-07075-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481000","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}

The traditional HF purification method produces a large amount of fluorine-containing wastewater, harming the environment. The environmentally friendly alkali-acid purification method avoids the generation of fluorinated wastewater. Herein, natural flake graphite sourced from Linkou County, Heilongjiang Province, is utilized as the primary material to address the challenge of low purity encountered in conventional alkali-acid purification methods. In addition, the response surface method is used to optimize the temperature, mass concentration and liquid-to-solid ratio of the hydrothermal alkali dissolution step in the purification process. To enhance the purification process, an integrated alkaline-acid approach is proposed, including a pretreatment step, the incorporation of co-solvents and the implementation of multiple acid-leaching stages. The x-ray diffraction (XRD), scanning electron microscopy (SEM) and x-ray fluorescence spectroscopy (XRF) measurements were used to characterize the purification effect. Experimental results show that through combined pretreatment, alkali dissolution and acid leaching, the fixed carbon content of graphite can be increased from 94% to 99.96%. The alkali-acid purification method greatly improves the purity of graphite and provides good potential for graphite in various industrial applications.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1494 - 1504"},"PeriodicalIF":2.1,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481019","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}

Electron back-scatter diffraction (EBSD) showed that the plain 6061 build had large, columnar grains with intergranular solidification cracking, while the inoculated build had a near-equiaxed, fine grain microstructure with no solidification cracks. By combining EBSD and energy dispersive spectrometry, the inoculated build has been shown to have exhibited globular growth while the non-inoculated build displayed a dendritic microstructure. A combination of heat transfer and modified grain morphology models were employed to predict the solidification morphology of the 6061 builds, which closely matched experimental results. A modification is proposed to the criterion marking the transition from globular to dendritic growth that better matches experimental results in this work. The results of this study are expected to provide improved methods to predict solidification microstructure for the development of new materials and processing parameters for additive manufacturing.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1423 - 1437"},"PeriodicalIF":2.1,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11837-024-07066-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480870","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}

The model parameters are optimized using the artificial neural network (ANN) method, and the model can mimic the change rule about thermal conductivity with temperature during the freezing process. Meanwhile, the time-varying law during the freezing process of the coal body is numerically analyzed using the thermal conductivity hyperbolic model and heat conduction theory; simulation results are analyzed and compared with measured results. After optimizing three parameters of the thermal conductivity hyperbolic model with the ANN approach, the calculated thermal conductivity values are distributed on a 1:1 line with measured results. This indicates that combining heat conduction theory with the thermal conductivity hyperbolic model can accurately predict the time-varying characteristics of temperature during the freezing process of the coal body with moisture content. Moreover, when coal body water capacity is about 12%, and its temperature decreases the fastest during freezing process This method establishes a theoretical foundation for forecasting the temperature aging properties of rapid freezing during the rock cross-cut coal removal process.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1395 - 1405"},"PeriodicalIF":2.1,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480871","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}
