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}

The results indicate that the stable flow state of the stress–strain curve of Ti-5Al-5Mo-5V-1Cr-1Fe alloy is rapidly reached within a small strain range (&lt; 0.1). The majority of flow curves exhibit horizontal plateaus, which is attributed to the rapid equilibrium between dislocation accumulation and annihilation.

During hot deformation, there are phase transformations and several softening mechanisms, including lamellar spheroidization, dynamic recrystallization, dynamic recovery and their interactions. The <i>β</i> transition structures are cut by a large number of interleaved <i>α</i> lamellar structures, and the <i>α</i> lamellar structures are participated in coordinated deformation, which promotes the enhancement of strength and plasticity of Ti-5Al-5Mo-5V-1Cr-1Fe alloy.

Meanwhile, experiments found impacts of impurities, such as Si, on the formation of the Al₃T phases; the mechanism is not fully understood. We here investigate effects of Si solution on the stability and crystal chemistry of the Al₃T phases using first-principles density-functional theory. The study has revealed a rich variety of effects of Si solution on the Al₃T phases. Si solution stabilizes the D0₂₂-Al₃Ti structure so that it becomes the ground state, taking over the binary D0₂₃ phase. Si solution in D0₂₂-V occurs only at elevated temperature. Si solution has little impact on the Al₃Sc phase relationship.

Comprehensive analyses of carbide banding distributions under different parameters were analyzed using optical microscopy, electron probe micro-analysis, electron backscatter diffraction and scanning electron microscopy. The findings reveal that the carbide banding grade is reduced from CZ7.6 to CZ7.1, and the average diameter of the carbide particles decreases from 667.51 nm to 287.37 nm under the application of the pulsed magnetic field.
