This paper systematically investigates the effects of adding 1.0 wt% TiC nanoparticles on the microstructure and tensile properties of nickel-based superalloy (IN738LC) prepared by electron beam powder bed fusion (EB-PBF). The results show that the adding of TiC nanoparticles promotes the nucleation of new grains while inhibiting the growth of the original grains, reducing the grain width from 82.09 μm to 28.55 μm. After the addition of TiC, the average size of the secondary γ′ phase decreased by 73.2 %, while the average size of the primary γ′ phase increased by 114.2 %, and the overall amount of γ′ phase increased by 80.6 %. In addition, the average size of MC carbides increased by 17.16 %, and their quantity increased by 96.2 %. At room temperature, the ultimate tensile strength and elongation at fracture of the composite (1.0 wt% TiC/IN738LC) improved by 23 % and 77 %, respectively. Post-tensile testing, the composite exhibited more and larger dimples, with more carbides within the dimples, thus enhancing the alloy’s ductility. The strengthening mechanism of the primary γ′ phase mainly relies on dislocation pile-up and bypassing, improving the material’s strength; the secondary γ′ phase primarily enhances ductility through dislocation cutting. MC carbides cause more dislocation pile-up, further improving the alloy’s resistance to deformation. This paper provides new insights for the development of high-performance nickel-based superalloys.</div></div>","PeriodicalId":383,"journal":{"name":"Materials & Design","volume":"251 ","pages":"Article 113723"},"PeriodicalIF":7.6,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inconel 718 and GRCop42 are commonly used for such components. However, the bimetallic joining of these alloys has been shown to result in a liquid miscibility gap at the interface, which at select compositions can lead to brittle phase formation and cracking. In this work, CALPHAD modeling is used to predict regions of brittle phase formation in the Inconel 718–Ni–GRCop42 and Ni–Cu GRCop42 multi-component ternary systems, with experimental validation of the modeling provided by arc melting. Through characterization of arc melted sample microstructure combined with CALPHAD modeling, the solidification paths throughout the system are elucidated and a brittle phase and crack free compositional region is identified. Based on these results, a compositionally graded path consisting of two transition compositions is identified. Powder Laser Directed Energy Deposition is used to fabricate the Inconel 718–GRCop42 joint with the identified transition compositions, and the joint is subject to characterization in terms of composition profile, defects, grain morphology, present phases and microhardness.

Moreover, computationally affordable models are typically limited to defect-free single crystals, omitting microstructural effects that strongly influence the material’s behavior.

We have established an advanced in-situ testing environment to continuously record the load–displacement of the indenter while simultaneously collecting the material’s deformation response to uniform uniaxial compression. This dynamic approach allows the evaluation of the orientation-dependent elastic strain components and the macroscopic uniaxial compressive stresses, each over time, enabling a differential analysis to assess the elastic and X-ray elastic constants.

The present work describes the fabrication of a high silicon content electrical steel alloy (Fe-6.5wt%Si) using directed energy deposition (DED), coupled with oxide inclusions to mitigate core energy losses. Abnormal Grain Growth (ABG) was observed after thermal post-processing at 1000 °C for 24 h (1000–24), together with the creation of oxide inclusions mainly around the grain boundaries. Magnetic properties were assessed through dynamic and quasi-static measurements for both as-printed (AP) and 1000–24 samples.

Dynamic magnetic analysis demonstrated an improvement of 39.2% in the total core losses of the 1000–24 sample (2088.8 J/m<sup>3</sup>), compared to the AP sample (3436.9 J/m<sup>3</sup>). The microstructure of the 1000–24 sample revealed the formation of Goss texture via ABG, ultimately decreasing the static hysteresis loss. Furthermore, an improved electrical resistivity compare to conventional electrical steel alloys was demonstrated at 119 μΩcm for the 1000-24 sample, and 105 μΩcm for the AP sample.
