Traditional methods for microcrack analysis essentially rely on manual detection, which poses challenges in accuracy and efficiency. The present investigation deals with a novel and highly effective strategy for detecting, classifying, and analyzing fatigue microcracks in Ti-6Al-4 V (TC4) titanium alloy with artificial intelligence (AI) in the context of deep learning. By integrating <em>in-situ</em> scanning electron microscope (SEM) images and convolutional neural network (CNN) algorithm, we propose a PGI-CrackNet model that is able to detect microcracks of length around 15 μm and thereby effectively outperform the detection capabilities of traditional models. Based on fracture mechanics models, the proposed model is capable of automatically identifying the main stages (i.e., initial crack, type I crack, type II crack, and break) in the formation of microcracks. Simultaneously, the proposed model bridges the gap between the AI-based image analysis and the physical crack propagation models, enabling the extraction of key information such as microcrack length and width, and further supporting the analysis of fatigue crack growth rates associated with various microcrack stages. The model could discover that in the initiation stage, the crack of TC4 titanium alloy grows at a fairly slow rate (∼3.6 μm/cycle) and occupies most of the crack life cycle. After the initiation stage, the crack first propagates as the type I cracks with a significantly faster crack growth rate (∼50 μm/cycle). Then, the type II crack occurs with a substantially reduced growth rate (∼25 μm/cycle). In the final stage, as the microcrack reaches a critical size, the growth rate increases sharply, leading to break. In summary, this improved PGI-CrackNet-based model enables more accurate tracking of crack growth over the fatigue life of materials and better classification of crack types based on their propagation mechanisms, making it highly suitable for early warning applications of material failure.</div></div>","PeriodicalId":10650,"journal":{"name":"Computational Materials Science","volume":"252 ","pages":"Article 113795"},"PeriodicalIF":3.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plastic deformation and fracture at the microscale have not been widely investigated because of the complexity of carrying out in-situ experiments. In this study, a combined crystal plasticity and phase-field fracture constitutive model for hexagonal close-packed crystal structures is developed, which can simulate the fracture behavior of the alpha phase of AM titanium alloys. An anisotropic thermal expansion model is established to capture the residual stress during the cooling process and its effect on subsequent plastic deformation and fracture. The simulated strain to failure is calibrated with experimental data. The model exhibits strong anisotropy, which agrees with experimental results. Based on the developed model, the influence of microstructural features on the fracture behavior of alpha-Ti is systematically investigated. The findings reveal that grain shape and orientation significantly affect the strain to failure and crack propagation paths of alpha-Ti.

The strain failure appears to be higher when load is applied along the maximum principal axis of the grains. The introduction of residual stress increases the final strain to failure in the model; this is interpreted as an acculation of compressive stress in elongated grains with the c axis approximately perpendicular to the load. Furthermore, by altering the local stress distribution, residual stress influences the crack propagation paths. This work provides useful insights into the crack initiation and propagation mechanisms of AM alpha-Ti. The simulation results can also provide guidance for process design such as adjusting scan direction and speed to optimize the microstructural characteristics and, consequently, improve the macroscopic mechanical properties of the material.</div></div>","PeriodicalId":10650,"journal":{"name":"Computational Materials Science","volume":"252 ","pages":"Article 113767"},"PeriodicalIF":3.1,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes and develops a new approach to the description of the tensile stress–strain curve based on the Yield Volume Fraction (YVF) function. The YVF description provides an excellent match to experimental stress–strain curves based on a physically meaningful parameter that corresponds to the cumulative volume fraction of the polycrystal that undergoes yielding during monotonic deformation. The statistical nature of the polycrystal yield phenomenon is highlighted by the fact that the YVF model achieves good agreement with observations when the lognormal and extreme value distributions are employed to express the cumulative density function for the total yield volume fraction, and the probability density function for the incremental yield volume fraction, respectively. This proposed approach is compared with crystal plasticity finite element (CPFE) simulations and different constitutive equations, along with experimental observations. The results highlight the potential of more extensive use of statistical methods in the description of material deformation response for improved design.</div></div>","PeriodicalId":10650,"journal":{"name":"Computational Materials Science","volume":"252 ","pages":"Article 113796"},"PeriodicalIF":3.1,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
