| 英文摘要 | Enhancing the fatigue strength of materials by increasing their tensile strength is generally considered as an effective strategy. This study observed a fatigue strength plateau in TC11 alloy: despite significant variations in tensile strength, the fatigue strength of TC11 alloy demonstrates remarkable stability. It is determined that this anomalous behavior is governed by a unique fatigue cracking mechanism associated with the primary alpha phase (alpha p) in dual-phase titanium alloys due to the pilling-up of dislocations and consequent cleavage (pillingup-cleavage). Under this mechanism, the critical cracking stress is predominantly influenced by the pilling-up distance of dislocations (reflected in the size of alpha p phase) and is relatively independent of the lattice frictional resistance (expressed in the nanoindentation hardness of alpha p phase). This leads to the occurrence of fatigue strength plateau in TC11 alloy in this study. |
