The proposed model integrates a Convolutional Neural Network (CNN), a Long Short-Term Memory Network (LSTM), and FNet that combines frequency domain analysis, in a parallel structure to extract features from the loading paths of materials. These extracted features are then connected to a fully connected neural network to predict fatigue life. The model was validated using fatigue data collected from 6 different materials, encompassing 17 loading paths and 336 samples. Additionally, ablation experiments were conducted, and the extrapolation capabilities were evaluated using specifically designed test sets. The results demonstrate that the proposed model exhibits excellent predictive performance and extrapolation capabilities.

In this paper, we conduct rotary bend fatigue experiments of nitinol wire to 2 billion cycles, measure the inclusion from which the crack initiated, and calculate the stress intensity threshold. Inclusion size is compared to the size of a unique feature observable with a scanning electron microscope which appears as a smooth area surrounding the inclusion and only on specimens that fractured after > 10 million cycles. The hypothesis presented is that the smooth feature around the inclusion is the growth of a small crack which continues until it reaches a size large enough to cause conventional fatigue crack growth. Relating inclusion size to that of the smooth feature creates a damage curve that can be written as a function of cycles to fracture. This damage curve may be useful to estimate the critical size of the largest allowable defect based on the design life and applied loading of the nitinol component.</div></div>","PeriodicalId":14112,"journal":{"name":"International Journal of Fatigue","volume":"190 ","pages":"Article 108613"},"PeriodicalIF":5.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142311059","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}

It is generally accepted that over-ageing has a large influence on the behaviour of these materials, however its effect on the fatigue strength is less understood. This work provides an experimental investigation of the effect of over-ageing on high cycle fatigue strength in both tensile and torsional loading conditions. It is shown that the torsional fatigue strength is more sensitive to over-ageing when compared to the tensile fatigue strength and that the fatigue defect sensitivity is negligible for torsional loads, in contrast to tensile loading conditions. The experimental results indicate that this is due to a change in the crack initiation mechanism, going from initiation in the matrix for torsion loads to initiation from casting defects for tensile loads. An original two-steps approach is proposed to rationalise the effect of over-ageing on the fatigue strength, with particular emphasis on decoupling the respective contributions from defects and the mechanical properties. This approach is used to build normalised Kitagawa-Takahashi diagrams that highlights the reduced defect sensitivity under tensile loads for the most severe over-ageing condition.</div></div>","PeriodicalId":14112,"journal":{"name":"International Journal of Fatigue","volume":"190 ","pages":"Article 108615"},"PeriodicalIF":5.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142320001","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 impact of α-lamella crystallographic and spatial orientations on fatigue crack propagation in an as-forged TiB/near α-Ti composite was investigated using innovative quantitative tilt fractography and electron backscattered diffraction techniques. Crack initiation was observed from TiB cluster defects, followed by faceted fatigue crack propagation across α lamellae. In long-life failure, facet formation appears to be driven by a combination of slip and resolved normal stress across the facet plane, with facet angles relative to the loading direction (LD) predominantly ranging between 30.0° and 50.0°. In contrast, short-life failure exhibited shear deformation as the primary mode, with facet angles relative to LD mainly between 40.0° and 50.0°. Crystallographic orientation analysis revealed that facets predominantly formed near the basal plane in both long-life and short-life failures. Crack-initiation microstructural neighborhoods favoring basal slip increased effective slip length over α lamellae, reducing resistance to crack propagation. This led to a rise in basal geometrically necessary dislocation (GND) density from 1.2 × 10<sup>13</sup> m<sup>−2</sup> in long-life to 3.6 × 10<sup>13</sup> m<sup>−2</sup> in short-life failures.

The improved yield strength is primarily obtained from grain refinement, deformation-induced martensitic, and high density of dislocations and deformation twins. The superior fatigue resistance is attributed to the synergistic effect of a reduction in surface and subsurface defects, dense dislocation substructure, high-strength martensitic phase, and a high amplitude of compressive residual stress (CRS) within the gradient deformation layer, collectively suppressing crack initiation. Microstructure evolution and CRS relaxation behavior of UNSM-treated samples during cyclic loading were examined. The results revealed that the benefits of CRS are relatively constrained due to its rapid relaxation under cyclic loading at a moderate stress level (550 MPa). In contrast, the gradient nanostructure remained stable under cyclic loading at the same stress level, exhibiting limited plastic deformation and grain coarsening. This indicates that the gradient nanostructure plays a more significant role than the CRS in delaying fatigue crack initiation and propagation at high stress levels.
