This study proposes a multi-objective field-driven design strategy. Using laser powder bed fusion (LPBF) technology, we fabricated multi-layer lattice structures from 316 L stainless steel, including isotropic (IWP-IWP) and anisotropic (IWP-D) configurations. Through quasi-static compression experiments, finite element simulations, and theoretical predictions, their compressive behavior, energy absorption characteristics, and deformation mechanisms were systematically investigated. Results demonstrate that multi-layer structures exhibit significant performance enhancements over primary structures at equivalent densities. Specifically, the heterogeneous IWP-D-21% structure achieved maximum increases of 57.46% and 64.72% in yield strength and elastic modulus, respectively. While the IWP-IWP-27% structure achieved maximum increases of 76.11% and 59.87% in plateau stress and energy absorption per unit volume, respectively. The deformation mechanisms differ markedly: IWP-IWP exhibits “drum-shaped” deformation, while IWP-D demonstrates uniform overall deformation. The established finite element model based on Johnson-Cook constitutive mechanics accurately predicts mechanical properties with an error below 9.82%. This strategy opens new avenues for designing high-performance multifunctional lattice structures in fields such as aerospace critical load-bearing components.</div></div>","PeriodicalId":383,"journal":{"name":"Materials & Design","volume":"263 ","pages":"Article 115588"},"PeriodicalIF":7.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146185960","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}

The effects of bonding temperatures on the interfacial microstructures, mechanical properties, and fracture mechanisms were systematically investigated. An exceptional joint tensile strength exceeding 1 GPa was achieved at an optimal bonding temperature of 850 °C. This is attributed to the formation of a continuous, ultra-thin nanocrystalline Fe<sub>2</sub>Nb reactive layer (RL) at the 18Ni350/Nb interface, coupled with a well-bonded, intermetallic-free HEA/Nb interface. However, increasing the temperature to 1000 °C thickens the Fe<sub>2</sub>Nb RL to over 300 nm and promotes grain coarsening, reducing the joint strength to 747 MPa. Correspondingly, the fracture mode transitions from a complex path involving both interfaces and the interlayer at low temperatures to preferential fracture along the thickened Fe<sub>2</sub>Nb RL at 1000 °C.
