We applied this approach to a 77 wt% IN718 and 23 wt% SS316L blend (77.IN718), selected for its potential for grain refinement during homogenization. After screening 1944 double-step aging profiles, the simulation identified an optimized treatment (725 °C/8 h + 600 °C/8 h) predicting a yield strength of 1070 MPa, which closely matches the experimental value. Despite a significant reduction in niobium and titanium content relative to standard Inconel 718, the new alloy 77.IN718 achieved performance (1055 MPa yield strength, 1285 MPa ultimate tensile strength, and 19.5% elongation) comparable to bulk IN718 processed by conventional manufacturing at room temperature. This work demonstrates a successful integration of ICME-enabled design and experimental validation, offering a sustainable and efficient pathway for developing high-performance alloys by blending existing commercial feedstocks.

With advances in additive manufacturing (AM), laser powder bed fusion (LPBF) is increasingly used to fabricate near-net-shape implants and scaffold structures, which can further reduce the Young's modulus. This paper comprehensively reviews the design and fabrication of β-Ti alloys with low Young's modulus, focusing on the alloy design, manufacturing of products via LPBF, and their joint effects on the regulation of Young's modulus. Specifically, β-Ti alloy design principles are systematically reviewed, focusing on the optimization of chemical composition, microstructural control, and emerging methodologies for predicting and tailoring mechanical properties. Furthermore, the influence of LPBF processing parameters and strategies on microstructure, texture, and mechanical properties is introduced, highlighting current achievements in the modulation of Young's modulus from the aspects of alloy fabrication. As a key advantage of AM, particular attention is given to the manufacturing of complex scaffold structures, which enable the regulation of wide-range stiffness through structural design. Moreover, challenges and limitations of β-Ti alloys with low modulus in the aspects of alloy design, LPBF, and design of scaffold structures are discussed. Overall, this review demonstrates state-of-the-art achievements on the fabrication of low-modulus β-Ti alloy via LPBF, providing systematic insights on the manufacturing of next-generation orthopedic implants with high precision and outstanding properties.</div></div>","PeriodicalId":101164,"journal":{"name":"Smart Materials in Manufacturing","volume":"4 ","pages":"Article 100143"},"PeriodicalIF":13.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148523773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results reveal that a 40 h-milling duration is feasible for Fe-Zn alloys to achieve sufficient solid solubility and effective grain refinement. The synergy of solid solution strengthening and grain refinement (from 11.47 ± 3.19 μm in pure Fe to 5.24 ± 0.63 μm in Fe-5Zn alloy) mainly contributes to improved mechanical strength (from 681.9 ± 11.7 MPa for pure Fe to 787.9 ± 15.5 MPa for Fe-5Zn alloy) in Fe-<em>x</em>Zn alloys (x ≤ 5 at.%), while Fe-10Zn alloy shows compromised mechanical strength due to excess precipitation of FHP-induced Fe₃Zn₁₀ phase.

The SWPUA dispersions were then combined with AM to fabricate photo-crosslinkable hydrogel resins suitable for high-resolution LCD printing. By varying the SWPUA:AM ratio and crosslinker content, the swelling behavior, gel content, mechanical properties, and adsorption performance of the 3D-printed hydrogels could be systematically tailored. Methylene blue (MB) was used as a model dye to evaluate adsorption performance. The 3D-printed SWPUA-AM hydrogels exhibited effective MB removal, with the highest Langmuir maximum adsorption capacity of 6.96 mg g⁻¹ obtained for the SWPUA:AM_75:25 formulation. Adsorption kinetics were best described by the pseudo-second-order model, while equilibrium data followed the Langmuir isotherm, suggesting surface-interaction-controlled adsorption and monolayer adsorption behavior.
