“…The holding time seems to have no effect on the increasing rate and the saturation values of maximum stress, which is a very common tendency for high-temperature materials. [52][53][54] The increasing temperature resulted in a significant reduction of the saturation values of maximum stress, as shown in embedded figure in Figure 5B, although it has no effect on the increasing rate of maximum stress in the first few cycles. The varying experimental results denote the strong interactions between creep and fatigue, which can be further analyzed by microstructure observations for deeper understanding of the variations of macroscopic phenomena.…”

Investigations into creep-fatigue life and the corresponding failure physical mechanism are crucial for guaranteeing the structural integrity of components.In this work, a series of strain-controlled fatigue and creep-fatigue tests were performed at different temperatures. Then, the EBSD-TEM combinative analysis was performed to reveal the microstructure evolution. The creep failure parameter dependence derived from standard creep experimental data and their importance in further creep-fatigue employment were discussed. Resultsshow that strain energy density has better relevance than ductility in connecting with creep failure. The temperature-dependent critical strain energy density and an equivalent failure strain energy density, considering geometric effect, were incorporated with the current energy-based model, which enables creep-fatigue life scatter within a factor of 1.5. Moreover, multi-slip activations and severe slip interactions under creep-fatigue conditions were responsible for the ultimately lifetime reductions based on microstructure observations.

“…Tsukada et al studied the correlation between defect energy and ferromagnetic phase precipitation in creep fracture experiments of 304 SS at 873 K [25]. Based on the above references, the current research on the creep temperature of 304 SS is mainly focused on 300-650 • C, i.e., the service environment temperature, and the research on the creep stage is also mainly the creep damage stage [26][27][28][29][30], and there is no consideration of the use of creep for the forming and manufacturing of 304 SS components. CAF primarily utilizes the first and second stages of creep to form the components at low temperatures for a short period of time, and there is yet to be a report on the mechanism of the CAF of stainless steel [17].…”

The creep deformation behavior and age strengthening behavior of 304 stainless steel under high stress levels were systematically studied by uniaxial creep test, tensile test, XRD diffraction test and transmission electron microscopy. The results show that the total creep strain and the initial creep strain rate increase with the increase in stress level, and the creep strain in the whole aging process is mainly produced in the initial creep stage. The calculated stress exponent shows that the main mechanism of creep deformation of 304 stainless steel at 453 K is dislocation slip. The strength and plasticity of 304 stainless steel after creep aging are improved simultaneously. Microstructural observations indicate an increase in dislocation density and martensite content, as well as austenite and twins, leading to an improvement in strength and plasticity, respectively. In addition, considering the influence of dislocation density on creep behavior, the relative dislocation density increase is introduced into the hyperbolic sine creep model, and a simple mechanism-based creep aging constitutive model is established. The creep strain predicted by the model is in good agreement with the experimental data of 304 stainless steel. The findings can provide theoretical support for the application of creep age forming in 304 stainless steel parts.

“…Poczklan et al 42 compared critical plane models for multiaxial low‐cycle fatigue tests of 316 L SS. Xu et al 43 evaluated creep‐fatigue life of type 304 SS under non‐proportional loading. Hassan et al 44 analyzed the influence of non‐proportional loading on ratcheting responses of SS and compared two cyclic plasticity models.…”

The focus of this study is to investigate the impact of cyclic loading path and temperature on the mechanical behavior of AA2024 aluminum alloy, a material commonly used in the aerospace industry. Our study aims to understand the cyclic evolution of work hardening (isotropic and kinematic) in response to different loading paths: tension‐compression cycles followed by equivalent torsion cycles, and vice versa. We also perform microstructural investigations using a scanning electron microscope (SEM) to gain insights into the evolution of fatigue damage during cyclic loading. By examining these factors, we aim to provide insights into the material's mechanical behavior and anisotropy. This research contributes to improving our understanding of the performance of AA2024 alloy under cyclic loading conditions.
