Friction Stir Welding (FSW) based technologies offer a solid-state joining and processing approach that significantly reduces energy input, material waste, and environmental impact compared with conventional fusion welding methods, making them at the forefront of sustainable manufacturing. By enabling high-integrity joints without the use of consumables, shielding gases, or post-processing treatments, FSWBTs exemplify how advanced manufacturing technologies can directly support the global transition toward cleaner, safer, and more resource-efficient production systems. This review examines FSWBTs in terms of manufacturing sustainability by analyzing their operational principles, industrial implementations, and sustainability contributions. The FSWBTs family, including Friction Stir Welding (FSW), Friction Stir Processing (FSP), and Friction Stir Additive Manufacturing (FSAM), operates in the solid state at sub-melting temperatures, using non-consumable rotational tooling that generates thermal energy and plastic deformation for bonding and material processing. This analysis examines the environmental advantages of FSWBTs, including reduced emissions, elimination of consumables, and enhanced product lifecycle performance. This review assesses the energetic benefits of FSWBTs, focusing on reduced energy requirements, improved process efficiencies, and enhanced productivity. The material conservation aspects and recyclability of FSWBTs were examined, with an emphasis on optimizing material utilization and directly reusing metal waste. This review examines FSWBTs applications in sustainability-focused industries, including electric mobility and renewable energy generation. Methods for sustainability optimization in FSWBTs implementation include tool geometry refinement, process parameter optimization, strategy-assisted FSWBTs, and integration with Industry 4.0. Additionally, developments in the FSWBTs field, which highlight its potential to advance sustainable manufacturing, have been addressed. This analysis highlights the crucial role of FSWBTs as enablers of sustainable manufacturing.</div></div>","PeriodicalId":54332,"journal":{"name":"Journal of Materials Research and Technology-Jmr&t","volume":"38 ","pages":"Pages 1-29"},"PeriodicalIF":6.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we fabricated Ti/steel clad plates via hot rolling using symmetrical assembly (SA) and double-layer assembly (DA) methods. Through comprehensive microstructure characterizations and finite element method (FEM) analysis, we elucidated the influence of assembly configurations on microstructural evolution and mechanical properties. The results show that the DA method achieved higher bonding strength with a single rolling pass than the SA method with two passes, indicating a more efficient bonding process. In the SA method, the symmetric geometry concentrated the overall deformation of the clad plates on the Ti side during rolling, leading to interfacial sliding and accelerating the thinning of the Ti side thickness. This degraded the interfacial bonding strength and triggered geometric dynamic recrystallization (GDRX) on the Ti side. In contrast, the asymmetric DA geometry promoted shear deformation in the steel side, ensuring comparable thickness reduction in both Ti and steel, thereby enhancing the interface bonding strength and deformation coordination between the components. Additionally, direct Ti-roller contact in DA not only improved the surface finish but also reduced the difference in deformation resistance between Ti and steel plates through heat transfer. The continuous dynamic recrystallization (CDRX) in the Ti side of the DA samples, produced finer grains and higher geometric necessary dislocation (GND) density. The combined effects of higher work hardening in the matrix and robust interfacial bonding contribute to the enhanced tensile properties observed in DA clad plates.

In particular, architected CuCrZr alloy lattices with feature sizes as low as ∼320 μm, smooth surface finishes, and high-fidelity inner architected topologies are engineered. It is observed that sheet-based, single-phase architectures allow for substantially enhanced stiffness, specific strength, and effective heat conductivity attributes, compared to equal-weight, solid TPMS designs. Moreover, IWP-based, CuCrZr–AlSi10Mg IPCs with superior load-bearing capacities are engineered (up to ∼420 MPa), along with Gyroid-based IPCs, furnishing exceptional energy absorption attributes (toughness ∼105 MJ/m<sup>3</sup>). Their high specific energy absorption (up to ∼23 kJ/kg) is combined with extraordinary effective thermal conductivity values (∼280 W/m·K), attributes highly desirable in applications requiring combinations of high strength and efficient heat dissipation. The findings highlight the effectiveness of hybrid manufacturing techniques in the engineering of architected materials and IPCs, laying the foundation for the development of a novel class of multifunctional, architected advanced materials, with thermomechanical attributes beyond the performance range of available designs.</div></div>","PeriodicalId":54332,"journal":{"name":"Journal of Materials Research and Technology-Jmr&t","volume":"38 ","pages":"Pages 674-691"},"PeriodicalIF":6.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144748565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
