In this study, we employed a novel low-energy electromagnetic pulse grain refinement device to systematically investigate the suppression effect of electromagnetic energy on solidification-induced hot tearing in aluminum alloys. The effects of current intensity and magnetic field frequency on the grain size, phase precipitation, and solidification shrinkage stress during the solidification process of aluminum alloy was systematically analyzed. The study found that the magnetic field concentrated precipitates at grain boundaries, with a small amount dispersed inside the grains, mainly consisting of θ(Al<sub>2</sub>Cu), T(AlZnMgCu) and T(Al<sub>2</sub>CuMg) phases. With increasing current intensity and magnetic field frequency, the content of precipitated phases gradually increased, and the layered precipitated phase at the grain boundaries changed to a block-like structure. The application of the magnetic field shortened the solidification shrinkage stress curve’s plateau, greatly improved the compensation ability of the residual liquid metal shrinkage, and reduced the tendency of hot tearing. Simultaneously, the pulsed magnetic field significantly refined casting grains. When the current was 30 A, the frequency was 30 Hz, and the duty cycle was 20%, the grain refinement rate reached 47.5%.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 9","pages":"6620 - 6636"},"PeriodicalIF":2.3,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896980","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}

In this work, it is proposed that, to adjust the slag composition in oxygen-enriched top-blowing nickel smelting, adding CaO instead of SiO<sub>2</sub> in the traditional process, to form a new slag composition that benefits and facilitates more efficient iron extraction. In this research, a suitable range of slag composition was selected through thermodynamic calculations under oxygen-rich top-blowing smelting conditions.

A predictive model for the melting temperature of the SiO<sub>2</sub>-MgO-FeO-CaO quaternary slag system was developed through optimization-derived design of experiments, A comparative assessment of the performance and phase composition between the new slag and traditional slag was conducted, and the results indicated that the hemispherical temperature of the modified slag decreased from 1410°C (traditional process) to 1382°C, and viscosity reduced from 0.173 Pa s to 0.071 Pa s. The properties of the slag can meet the requirements of nickel oxygen-rich top-blowing smelting.

In addition to contamination limits, battery manufacturers often specify the maximum level of dross that can be produced when melting a given alloy. This study presents, for the first time, an example of a method for determining the percentage of dross formed after melting an alloy. In addition, the effect of three different lead pyrorefining methods—traditional refining, traditional refining with the double addition of NaOH and NaNO<sub>3</sub> and an alternative method using metallic aluminum—on the percentage of dross produced during the melting of the PbSnCa alloy was evaluated. Industrial-scale experiments have revealed significant differences in the amount of melt dross formed, confirming the influence of the refining method on this parameter. The aluminum refining method gave a lower dross content than the traditional approach and showed the highest process stability. Microstructural and phase analysis indicated that the resulting dross consisted mainly of metallic lead mixed with oxide phases. The results highlight the potential of lead refining using aluminum and provide valuable insights into optimizing lead recycling practices, as well as being a valuable knowledge base for lead-acid battery manufacturers.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 9","pages":"6603 - 6619"},"PeriodicalIF":2.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11837-025-07558-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144897003","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}
