The results indicate that both severe pre-oxidation and elevated oxidation rates lead to surface crack initiation. In pre-oxidized specimens, surface recrystallization occurs early, triggering surface cracking and reducing fatigue strength at 10<sup>7</sup> cycles, though its effect at 10<sup>9</sup> cycles is minimal. At 1050 °C, the fatigue strength decreases markedly compared with 1000 °C, and cracks consistently initiate at the surface and propagation in Mode I. Thermal growth stress of oxides near the crack tip alters the local stress state, promoting γ’ rafting. Deformation accumulated at γ/γ’ interfaces, coupled with γ’ rafting and low-angle grain boundaries, accelerates aluminum diffusion, forming Al<sub>2</sub>O<sub>3</sub> as the dominant oxide.

The results indicate that the TMF life decreases as the peak temperatures rise from 400 °C to 500 °C. As the cyclic number increases, the maximum tensile stress shows slight cyclic hardening in the temperature range of 100 to 400 °C. Additionally, in the temperature range of 100 to 500 °C, the maximum compressive stress exhibits slight cyclic softening. The fatigue damage and crack propagation processes demonstrate that the tearing of vermicular graphite at the edge of the sample is the primary cause for fatigue crack initiation in the lower temperature range. The weakening region comprised of multiple vermicular graphite particles facilitates the gradual extension of cracks. At higher peak temperature, oxidation rapidly erodes the interface between the vermicular graphite and the matrix, which leads to the debonding of graphite and initiation of the fatigue cracks. The rapid oxidation effect accelerates the corrosion of the metal matrix, promoting crack propagation, which is the primary factor contributing to the reduction of fatigue life. Given the complexity and high cost associated with the TMF test, a method for predicting the TMF life by building the correlation between low-cycle fatigue and the TMF lives in terms of the hysteresis energy is proposed. This method enables rapid and accurate prediction of the TMF life through a relatively small amount of samples and simpler experiments, demonstrating significant industrial application potential.</div></div>","PeriodicalId":14112,"journal":{"name":"International Journal of Fatigue","volume":"197 ","pages":"Article 108931"},"PeriodicalIF":5.7,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644062","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 framework employs lightweight Temporal Convolutional Networks (TCN) for temporal feature extraction while considering frequency-domain features, and incorporates both static and cyclic material properties as structured inputs. The attention-based fusion mechanism enables adaptive integration of temporal and material features, enhancing the model’s ability to capture complex interactions between loading conditions and material characteristics. To validate this approach, a multiaxial fatigue dataset comprising 499 data points was established across six major categories of metallic materials. The model’s performance underwent rigorous evaluation using hierarchical nested cross-validation, while key features were identified through SHAP analysis and recursive feature elimination. Results demonstrate that the proposed unified model exhibits robust predictive performance, with TCN showing superior stability and efficiency compared to other temporal feature extraction methods. Furthermore, the study explores cross-material prediction, revealing that fine-tuning with a small proportion of new material data can significantly enhance prediction accuracy.

Firstly, sweep frequency and resonance fatigue tests of fuel piping system are conducted to determine the resonance frequencies, resonance strain responses and corresponding fatigue lives. The accuracy and effectiveness of the finite element model, as well as previously established fatigue life models for the components of the piping system, are then validated through deterministic modal and implicit dynamic analysis.
