 note = {To elucidate the micro-mechanism of fatigue crack growth (FCG), this study conducts a direct analysis of the crack tip using several electron microscopic techniques. Particular attention is paid to FCG within a precipitation-hardened alloy, specifically aluminum (Al) - 2.4% copper (Cu). A small specimen containing the target crack tip is cut from a fatigued bulk specimen, and the two-step ion beam polishing method is applied to analyze its cross-section. It was found that FCG is strongly related to the formation of a dislocation cell structure, the size of which depends on the applied stress intensity factor range, ΔK., Kansai University Expenditures for Support of Training Young Scholars (3D mapping of line defects around a fatigue crack tip: application of high-voltage STEM method, 2017-2018)., 2017年度 関西大学若手研究者育成経費「疲労亀裂先端の線欠陥3Ｄマッピング：超高圧ＳＴＥＭ法による挑戦」, KAKENHI 21H04536},
