To improve the stability and welding efficiency of titanium alloy cold metal transfer (CMT) welding, the CMT plus pulse (CMT + P) welding process, which is suitable for the welding of medium- and thick-plate titanium alloys, was first developed. This study aims to investigate the microstructure and mechanical properties of Ti-6Al-4 V alloy joints produced via CMT welding. These results indicate that the CMT + P welding mode is suitable for titanium alloys. The microstructure of the weld metal was composed of acicular <i>α</i>’ martensite, massive α, and Widmanstätten <i>α</i> + <i>β</i>. The microstructures of the fusion zone were composed of acicular <i>α</i> and a large amount of fine <i>α</i>’ martensite. The heat-affected zone consists of acicular martensite, a residual <i>β</i> phase, and an <i>α</i> phase. The maximum microhardness was observed in the fusion zone, the microhardness of the heat-affected zone decreased gradually, and the microhardness of the weld metal was equivalent to that of the base metal. The tensile strength of the joint was almost equal to that of the base metal, and the fracture locations of all the tensile samples were in the base metal, which was related to the element content and microstructure. The impact toughness of the welded joint of the CMT was 33% greater than that of the base metal. The fracture surface of impact toughness is typically ductile with many dimples.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 20","pages":"23171 - 23180"},"PeriodicalIF":2.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284347","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}

Field emission scanning electron microscopy, EDS analysis, and XRD results confirmed that the ceramic particles were successfully incorporated into the matrix. However, microstructural examination of the cast composites shows that non-uniform particle distribution was obtained and that it varies between the top to bottom of the Al-7Si/Al₂O₃ + ZrO₂ composite. Additions of Bi and Sn produced a better and more uniform distribution of Al₂O₃, ZrO₂, and SiC particles within the matrix. Elemental mapping confirmed that Bi is segregated into the eutectic Al-Si area at the particle/matrix interface. Tribological testing conducted under applied loads of 5, 10, and 20 N identified the minimum specific wear rate and friction coefficient obtained in the Al-7Si + Bi/ZrO₂ + Al₂O₃ + SiC composite treated with Bi, which exhibited the highest hardness (75 BHN), YS (122.2 MPa), and UTS (153.1 MPa). Obtained results revealed a transition from adhesive to a combined adhesive and abrasive wear mechanism, suggesting enhanced wear resistance. Three scenarios can be essential factors that lead to better distribution of particles and superior properties of hybrid composite: (i) Bi reduces the surface tension of the matrix and facilitates the incorporation of ceramic particles into the matrix alloy, (ii) Bi mitigates the discontinuity and improves bonding strength at the matrix/particle interface, and (iii) Bi may play a role as solid lubricant under wear conditions.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 20","pages":"23418 - 23434"},"PeriodicalIF":2.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284326","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}

Three different stacking sequences (SLG/CdS/Sn/Cu, SLG/Cu/Sn/CdS, and SLG/Cu/CdS/Sn/Cu) were used, followed by sulfurization at 550 and 580 °C. Structural analysis confirmed a tetragonal crystal structure with preferred orientation along the (112) plane, with the N3 series (SLG/Cu/CdS/Sn/Cu) free of SnS impurities. Increasing sulfurization temperature improved crystallinity, increased crystallite size, and reduced lattice strain and dislocation density. Morphological studies showed uniform, crack-free films, with the N3 series exhibiting near-ideal stoichiometry. Optical analysis revealed band gaps in the range of 1.32-1.37 eV, with lower band gap values for higher sulfurization temperatures. Electrical measurements demonstrated that N3-550 had the highest carrier concentration (3.5 × 10¹⁴ cm⁻³) and p-type conductivity, making it the most suitable candidate for photovoltaic applications.

The mechanism underlying the formation of this RD-texture component was also discussed. After recrystallization annealing, the T-HRSB processed magnesium alloy sheet exhibited an almost complete absence of both the initial basal texture component and the newly formed RD-texture component. Instead, a novel RD-split non-basal texture emerged, characterized by a basal pole tilted approximately 36° away from the ND toward the RD, along with significantly broadened contour lines. This distinctive RD-split texture was found to contribute to the excellent room temperature stretch formability of the AZ61 magnesium alloy sheet. In addition, the influence of texture on the mechanical properties and stretch formability of the AZ61 Mg alloy sheet at room temperature was investigated.

These AM technologies are today mature enough to be used intensively for the manufacturing of metal parts. Nevertheless, energy efficiency and productivity play a crucial role in scaling up AM to higher volumes, especially for their relatively slow deposition speed per unit mass compared to conventional manufacturing methods. To the current state of the art, the energy consumption analysis of these processes under real industrial conditions and not in a lab environment is of primary interest to contribute to reaching the sustainability development goals posed by United Nations. However, in the existing literature, very few of these consider real case studies typically faced in industry. Also, the existing research on AM production is mainly focused on the quality of produced parts and printing technology rather than factory-level management. Literature results demonstrate that discrete event simulation (DES) methods can successfully help to increase the productivity of conventional production systems. However, these methods have not yet been extensively reported for AM facilities. The aim of the work is dual: on the one hand, to provide reliable primary energy data to be used for carrying out LCA analyses on AM; on the other hand, to provide process guidelines and insights to reduce energy consumption in AM industrial operations. For this purpose, an experimental campaign has been carried out by using primary energy data of different printed jobs deriving from the same AM manufacturing cell. A DES has been also carried out to estimate the influence of schedule issues on real energy consumption. The results obtained showed that, under fixed process parameters, both the job schedule and the job design (in terms of the number and dimension of the parts printed) have a non-negligible effect on the energy consumption of the process.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 15","pages":"15315 - 15323"},"PeriodicalIF":2.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-025-11007-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832212","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}
