| Abstract: | On the base of the fatigue small cracks growth test in TA6V titanium alloy,the fatigue fracture of TA6V titanium alloy SENT specimen is analyzed.The fatigue fracture fractography of cracks origins zone and cracks process zone and quickly failure zone in the course of crack propagation have been observed by virtue of the Scanning-electron-microscope(SEM),and the forming reasons of the fatigue fracture fractography is analyzed in order to afford the scientific accordance for safety design and reliability analysis of a structural member in the fatigue. |
