Analyzed over 1,200 pores from high-resolution CT scans across specimens, extracting 3D shape features (volume, surface area, sphericity, aspect ratio) to evaluate their influence on fatigue performance. Calculated critical pore sizes for specimens using the Murakami model, incorporating maximum principal stress (up to 600 MPa) and stress factors (k = 0.8–1.0) to identify defects likely to cause early fracture. · Applied surface smoothing and mesh simplification to STL-reconstructed pores
