Titanium hydride (TiH₂) was selected as a precursor due to its improved sinterability, oxidation resistance, and affordability. The TiH₂–Nb alloy was produced through mechanical alloying and powder metallurgy, with optimisation using the Box-Behnken Design (BBD) method. Elemental TiH₂ (60 wt%) and Nb (40 wt%) powders were milled at various speeds (100 to 300 rpm), compacted at 500 MPa, and sintered under an argon atmosphere at temperatures between 800 °C and 1200 °C for 1 to 3 h. Response surface methodology (RSM) identified sintering temperature as the most influential factor on compressive strength and elastic modulus. Optimal conditions, milling at 200 rpm and sintering at 1200 °C for 3 h, yielded in a compressive strength of 1768 MPa and an elastic modulus of 8.7 GPa, closely matching human cortical bone properties. TiH₂–Nb alloy outperformed Ti–Nb alloy in terms of densification (98.56 % relative density), reduced porosity (1.44 %), and desirability score (0.9). Thermogravimetric (TG) analysis confirmed effective dehydrogenation at higher milling speeds due to enhanced Nb diffusion and defect density. X-ray diffraction (XRD) confirmed formation of a dual-phase α+β Ti structure. Optimised TiH₂–Nb alloys offer a promising alternative to Ti–6Al–4V implants, with reduced stress shielding and improved mechanical compatibility for future orthopaedic implants.</div></div>","PeriodicalId":47623,"journal":{"name":"Materialia","volume":"45 ","pages":"Article 102640"},"PeriodicalIF":2.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145841447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, this study proposes a conditional diffusion model (GCSA-CDDPM) enhanced by a global channel–spatial attention mechanism, validated on SLM-processed 316 L stainless steel. The proposed approach comprises three core strategies: (1) designing a unified pipeline for processing heterogeneous grain boundary images, enabling the construction of a high-quality, multi-scale, cross-literature dataset; (2) Putting forward the GCSA module with the process parameter embedding structure to enhance the image structure modelling and generation modulation capability; and (3) introducing a hierarchical breakpoint repair strategy to enhance boundary continuity. Experimental results demonstrate that GCSA-CDDPM surpasses baseline models in structural fidelity, scale conformity, and parameter responsiveness. It achieves the best performance in FID (33.04), grain size error (7.07%), and matching accuracy (92.93%), while producing visually superior images in terms of boundary integrity, noise suppression, and pattern stability. In addition, our findings confirm the model’s ability to capture implicit mappings across process parameters, microstructural morphology, and grain size evolution.

Herein, ZCO is directly grown on nickel foam (NF) via a hydrothermal reaction, developing a binder-free ZCO/NF electrode.

Further, the ZCO/NF was structurally and morphologically characterized by physicochemical techniques. When evaluated as an anode material for SIBs, it demonstrated outstanding electrochemical performance. The ZCO/NF exhibited an irreversible discharge capacity of 1893.73 mAh/g and a reversible capacity of 863.79 mAh/g at a current density of 10 mA/g, along with excellent rate capability. At a current density of 50 mA/g, it retains 42.12% of its capacity after 300 cycles.

We show that three types of oxides exist within the ferritic matrix: nanoclusters with a structure identical to that of the matrix, pyrochlore-structured nano-oxides, and, for the first time, intermediate-sized nano-oxides exhibiting a structure in the process of transforming into the pyrochlore phase. We conclude that the formation of nano-oxides follows a precipitation sequence in which metastable nanoclusters act as precursors to the pyrochlore-like nano-oxides. Understanding this pathway is crucial, as it not only enables control over oxide distribution (in terms of size and density), but also provides insights into the formation of interface structure, which governs point defect and helium trapping.
