However, its successful implementation critically depends on achieving effective and homogeneous alloying during the process — an outcome that is highly sensitive to the process parameters and remains challenging to predict. In this study, a process map incorporating the degree of <em>in-situ</em> alloying was developed for laser powder bed fusion (LPBF) of a titanium-tantalum binary alloy with 30 wt% tantalum (Ti-30Ta) by correlating single-track melt pool characteristics with bulk sample properties through the integration of machine learning and analytical modelling. This approach coupled and quantified the relationship between the melt pool mode and mechanical properties, refining the process window for the Ti-30Ta alloy system. Under the defined process window, fabricated Ti-30Ta bulk samples exhibited optimised mechanical properties, with an ultimate tensile strength (UTS) of 745.8 MPa and an elongation of 16.9 %. Synchrotron X-ray diffraction analysis confirmed that the microstructure is predominantly composed of orthorhombic α″ phase. Furthermore, the samples demonstrated enhanced biocompatibility and a favorable balance between structural density and alloy homogeneity, underscoring their broad application potential. Beyond its direct implications for Ti-30Ta alloy, this study establishes a transferable framework for <em>in-situ</em> alloying process maps development across various alloy systems, paving the way for more advanced alloy development and manufacturing strategies in the field of <em>in-situ</em> alloying AM and beyond.</div></div>","PeriodicalId":386,"journal":{"name":"Materials Science and Engineering: R: Reports","volume":"166 ","pages":"Article 101082"},"PeriodicalIF":31.6,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144826458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present an innovative microwave-assisted (MW) fabrication method to create a high disordered graphite as a catalyst-free cathode for enhancing the performance of an aluminum electrochemical energy system (Al-EES). Using MW-treated graphite with a catholyte ie., sodium persulfate (Na₂S₂O₈) eliminates the need for traditional oxygen reduction reaction (ORR) cathodes, raising the device voltage from 1.46 V to 2.02 V and achieving an energy density of 2314 Wh/kg_Al. As a result, the MW process enriches charge transfer pathways, increases active sites, and boosts the electrocatalytic performance of the Na₂S₂O₈. Advanced characterization techniques, including Raman mapping, scanning electrochemical microscopy (SECM), and density functional theory (DFT) calculations, confirm enhanced graphitization and functionalization, leading to improved efficiency. This innovation streamlines the electrode design by replacing complex, high-cost cathodes (catalysts, air-breathing layer, binder, etc.). It allows the modified graphite to serve as both cathode and bipolar plate, reducing system costs by 90 % compared to conventional Al-air batteries. The advancements result in a peak power density of 161 mW cm⁻², 2.5 times higher than Al-air systems, and exceptional discharge performance, setting a new standard for cost-effective, high-performance Al-based energy conversion devices.
