| Abstract: | On the basis of the fatigue test of Hi-Lock Pins inTi6Al4V itanium alloy,the fatigue fracture of Hi-Lock Pins in titanium alloy was analyzed.The fatigue fracture fractography of cracks origins zone and cracks process zone and quickly failure zone in the course of crack propagation were observed by virtue of the Scanning-electron-microscope（SEM）,and the shaping reasons of the fatigue fracture fractography was analyzed in order to afford the scientific accordance for safety design and reliability analysis of a structural member in the fatigue. |
