The optimal amount of Be was 0.06 wt.%, which resulted in almost the absence of the β-phase and the best aspect ratio of the α-phase and changed the coarse acicular Si to fibrous Si. However, the T4 heat treatment distributed the phases uniformly, but it could not inhibit the formation of the β-phase. The hybrid method led to the best results since the addition of Be caused the formation of the α-phase, prevented the formation of the β-phase and distributed the phases uniformly. Moreover, the fracture mode in the sample modified by the hybrid method was completely ductile while the other samples exhibited a contribution of brittle fracture to some extent.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"76 12","pages":"7002 - 7010"},"PeriodicalIF":2.1,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199384","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}

Thermodynamic analyses of ilmenite smelting were conducted to outline a path for process improvement. Specifically, the distribution of Ti and Fe, as well as a wide range of impurities, including V, Cr, Mn, Al, Si, Ca, Mg, P, and S, between the titania slag and molten iron were investigated. A comprehensive literature review was conducted to adequately ascertain the chemical compositions of ilmenite concentrates, which are among the most critical operational parameters in ilmenite smelting. Additionally, the quality requirements regarding impurity contents in the raw materials for TiO₂ pigment production were reviewed. The partition coefficients of elements between slag and metal determined as a function of process variables (i.e., oxygen partial pressure, temperature, and MgO/(Al₂O₃ + SiO₂) ratio) has been presented. Moreover, an in-depth analysis of the oxygen potentials during the ilmenite smelting process and the analysis of slag viscosity in corresponding process conditions have been shown. The analysis results are compared to the experimental data reported in the literature.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"76 11","pages":"6511 - 6533"},"PeriodicalIF":2.1,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199383","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}

Pal,&nbsp;Sudipto Chakraborty","doi":"10.1007/s11837-024-06817-7","DOIUrl":"10.1007/s11837-024-06817-7","url":null,"abstract":"<div><p>Electroless coating is such an area that has recently taken the research spotlight. Heat exchangers are the most used industrial equipment by chemical and mechanical firms. Of various other materials like copper, iron and carbon steel, it is considered that the structural units of these heat exchangers should be mild steel because the other metals are more porous in nature, encouraging corrosion, scaling and fouling. Mild steel is a revolutionary material that has a varied range of uses, from tiny needles to giant machinery. Easy market availability, material durability, great thermal efficiency and reasonable prices are the core reasons for this. However, the material has a few crucial disadvantages like corrosion, wear, fouling, pitting, etc. Electroless coating can be a good alternative to overcome these issues. These coatings can create novel nickel-based composite materials, of which Ni-P-Cu is the most common when the application demands the property of heat conduction. These coatings also provide great corrosion resistance. As our objective is the application of these composite coatings on heat exchangers, both corrosion and heat transfer properties have been demonstrated respectively in this study. The analysis has chosen electroless ENPC-coated mild steel at various concentrations of copper ranging from 0.2 g/l to 1.2 g/l. The surface morphology and elemental analysis have been explained using FESEM and EDX analysis. The material phase transformation has been observed using an XRD plot. The microhardness of the sample before and after the heat transfer study has been analysed and compared. The Tafel curve of the heated sample showed the increase of corrosion resistivity within the temperature range of 100°C to 400°C for an optimised coated sample ENPC-1, (i.e., electroless nickel phosphorous copper coating with copper concentration 1 g/l). A spray cooling setup built in house has been used to analyse the heat transfer mechanism. The cooling rate obtained for the ENPC-1 sample is around 25.2% more than in the previous studies on uncoated samples using base fluid (water).</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"76 11","pages":"6600 - 6614"},"PeriodicalIF":2.1,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199387","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}
