After the forming stage, a complex residual stress field is present in the workpieces. During the milling stage, a disturbance of the stress equilibrium can lead to workpiece distortion. A virtual modeling approach to predicting the residual stress-related geometric deviations is presented. This approach can be used to evaluate the influence of process control variables on deviations and to identify suitable parameter values for reducing them. First, the initial residual stress field at the beginning of the milling stage is determined based on a physical-mathematical model of the forming stage, considering the elasto-plastic properties of the sheet material. Subsequently, the geometric deviations resulting from material removal are modeled using a series of equilibrium calculations. For comparison, the manufacturing process chain was implemented experimentally, and measurements of the workpiece geometry using a tactile coordinate measuring system were performed. The resulting geometric deviations for two target geometries were used to validate the model predictions. The virtual model enabled the magnitude of the geometric deviations and the effectiveness of a two-step milling strategy to be predicted.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 10","pages":"7559 - 7575"},"PeriodicalIF":2.3,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11837-025-07700-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145078864","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}

However, the processing demands of laser powder bed fusion have limited the availability of materials that are amenable to 3D printing, motivating development of new alloys that have low defect susceptibility. High-throughput screening tools are necessary to evaluate these new alloys and decrease prohibitive development costs. Acoustic emission sensing utilizing a piezoelectric sensor is investigated as a method for in situ crack detection during single-track laser melting experiments which are set to replicate laser powder bed fusion processing conditions. Two materials found to exhibit either solidification cracking (CMSX-4) or solid-state cracking (TZM) are examined, ultimately showing the experimental setup can detect individual solid-state cracking events but not solidification cracking events. Calibration of the sensor with ball-bearing drop tests down to 0.04 <span>(upmu )</span>J provides a useful assessment of the sensitivity of the technique. Furthermore, the acoustic emission data can be used to determine relative differences in crack size with varying scanning parameters (laser power, scan speed) and gain insight into the crack initiation characteristics of the material.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 10","pages":"7274 - 7286"},"PeriodicalIF":2.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145078848","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}

Efficient impurity removal with minimal losses of valuable metals is essential for effective PLS purification. This study investigates the effect of CaCO<sub>3</sub> particle size (− 400 mesh) on precipitation performance, revealing an 11% improvement in aluminum removal efficiency compared to coarser particles. A two-stage precipitation process was found to be optimal. In the first stage (80°C, pH 3.0, 2 h), 96% Fe, 92% Al, and 97% Cr were removed, with minimal co-precipitation of Ni (1.04%) and Co (2.05%). The second stage (70°C, pH 4.5, 1.5 h) achieved 99.9% removal of Fe, Al, and Cr, though with slightly higher Ni loss (3.95%). Morphological analysis revealed that CaCO<sub>3</sub> produced crystalline residues, facilitating improved solid-liquid separation compared to the amorphous residues formed using NaOH and MgO. The thermogravimetric analysis confirmed superior moisture control in CaCO<sub>3</sub>-derived residues, showing only 2.88% mass loss at 115°C, significantly lower than residues from MgO and NaOH. These results provide practical guidance for impurity removal in HPAL operations and highlight the effectiveness of CaCO<sub>3</sub> as a neutralizing agent.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 10","pages":"7461 - 7475"},"PeriodicalIF":2.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079002","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}
