The methodology is the response surface methodology (RSM), allowing for a comprehensive evaluation of the effects. The study examines the influence of key welding parameters, such as laser power, welding speed, focal distance, and laser beam deviation from the joint’s center, on several response variables. These variables encompass the depth of the molten pool, the weld microstructure, and its mechanical characteristics. The depth of the molten pool, on the other hand, is primarily influenced by laser power and focal distance. Notably, a transition in microstructure is observed from columnar dendrites to a cellular configuration as one moves from the fusion line towards the center of the fusion zone. In the fusion zone of the duplex base metal, an unmixed zone is identifiable in the upper segments of the fusion line.

The effects of the TMP parameters on the microstructure of GBE were studied by electron backscattering (EBSD), and the effects of different TMP parameters on the microstructure and hardness of GBE were analyzed. The results show that different restraints have different mechanisms of grain boundary network formation, and that strain is the main mechanism of boundary migration.

To address this issue, the present work adopts a Bayesian optimization framework for the parameterization of face-centered cubic plasticity models while simultaneously considering multiple experimental datasets from the literature. For single crystal Cu, parameter optimization was guided by the tensile stress–strain curves along several crystallographic orientations, with an adequate fit being found for five orientations at once. While additional parameters allowed for the consideration of more physical mechanisms, like different slip system interaction strengths or misorientations inherent to the experimental data, the extra dimensionality was found to limit the efficiency of the global minimization procedure. For polycrystalline Ni, multiple grain sizes were considered together in a representative polycrystalline model, with the optimization able to reconcile the model with the data for three grain sizes at once. As meaningful interpretation of parameters relies on the uniqueness of their values, incorporating multiple datasets into this discerning parameterization procedure enables more robust prediction and application of crystal plasticity models.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 1","pages":"324 - 335"},"PeriodicalIF":2.1,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11837-024-06935-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859611","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}

Pulp chemical analysis revealed that copper minerals significantly deplete cyanide and dissolved oxygen. Surface analysis reveals that cyanidation enhances the wettability of copper minerals, transitioning them from hydrophobic to hydrophilic, thereby hindering the adsorption of flotation agents. The shift may result from CN<sup>−</sup> adsorption and the creation of hydrophilic compounds like CNO<sup>−</sup>, SCN<sup>−</sup>, CuCN, and CuSCN instead of iron-cyanide complexes. Further ToF-SIMS deep sputtering analysis shows that cyanide can infiltrate the surface layer of copper minerals, spreading into the bulk phase and contaminating the surface.
