Effect of Cold Expansion on Fatigue Life of Hole Structure of TC17 Titanium Alloy

Effect of Cold Expansion on Fatigue Life of Hole Structure of TC17 Titanium Alloy

In order to improve the fatigue performance of TC17 central hole specimen, the hole wall surface integrity was characterized by scanning electron microscopy (SEM), roughness meter, X-ray diffraction, and the influence of hole cold expansion(HCE) parameter on the fatigue performance of the hole speci...
