Therefore, we propose an idea whether we can systematically clarify the deformation coordination mechanism and weak interface of the complex structure in tensile, and then deeply analyze the local plastic deformation and cracking behavior of HCF. Here, tensile tests at different strain rates were conducted at 550 °C, 650 °C, 750 °C, and 850 °C. Multiscale characterizations were performed on the fracture surfaces and cross-sections. Subsequently, HCF tests were conducted and the secondary cracks during the initiation and propagation were analyzed. Results indicate that 750 °C is the tensile ductile-to-brittle transition temperature. The deformation capability of each phase increases with temperature, and the γ-phase and β-phase are the primary microstructures responsible for coordinated deformation. The γ-phase interfaces are weak regions susceptible to cracking due to dislocation accumulation, resulting from the strength-plastic mismatch between the γ-phase and α-phase or lamellar colonies. At 850 °C, a grain refinement layer forms on crack initiating-surface, leading to that the endurance property at 850 °C is abnormally high.</div></div>","PeriodicalId":14112,"journal":{"name":"International Journal of Fatigue","volume":"202 ","pages":"Article 109242"},"PeriodicalIF":6.8,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880202","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}

Numerically predicted crack initiation locations and trajectories agreed with the experimental means, with errors of 2.6 % and 8 %, respectively.

This study systematically investigates the effects of pre-strain and bake hardening on the LCF behaviour of hot-rolled high-strength steel HR420. Fatigue tests were performed across a strain amplitude range of 0.2 % to 0.8 % to assess the influence of bake hardening on cyclic softening behaviour and microstructural evolution. The fatigue fracture morphology and microstructural evolution were characterized by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Furthermore, a crystal plasticity finite element model incorporating the bake-hardening effect was established using EBSD-derived data to simulate microstructural evolution and predict fatigue life. The results show that at low strain amplitude (0.2 %), bake hardening significantly prolongs fatigue life by suppressing crack initiation, with a maximum increase of 90 % observed under 4 % pre-strained + bake hardening. In contrast, at higher strain amplitudes (0.4 % and 0.6 %), bake hardening accelerates crack propagation due to intensified stress localization, leading to a fatigue life reduction of up to 40 %. The simulation results are in good agreement with experimental observations, confirming the model’s predictive capability.
