an unusual Fatigue phenomenon duality of the s n Fatigue Curve in the β titanium alloy ti 10v 2fe 3al
Scripta Materialia, 2003Co-Authors: S.k. Jha, K Ravi S ChandranAbstract:Abstract An unusual Fatigue behavior, observed in the α + β microstructures of the β -titanium alloy, Ti–10V–2Fe–3Al, is reported. It is the duality of the S – N Fatigue Curve where the Fatigue data of specimens failing from cracks nucleated at the surface and subsurface regions grouped in to two separate S – N Curves. The microstructural factors causing this effect are analyzed.

Near threshold Fatigue Curve based on the dislocation free zone model of fracture
International Journal of Engineering Science, 1999Co-Authors: S.-j. ChangAbstract:Abstract Dislocation pileup along an inclined direction from a crack tip has been observed in metals during tensile deformation in an electron microscope. Dislocations are emitted from the crack tip, move through a dislocation free zone, and pile up in the plastic zone. The problem of inclined pileup of screw dislocations at a crack tip with a dislocation free zone has been solved by applying the Wiener–Hopf method. The result can be used to calculate the crack tip blunting and the local stress intensity K for the applied stress intensity K 3 . According to the Fatigue theory of Laird or Neumann, the crack propagation per cycle has the order of magnitude of the blunting. The blunting versus K 3 is then plotted. It has the shape of the near threshold Fatigue Curve. To plot this Curve, the local stress intensity K has been assumed to be the critical value K g for the dislocation emission at the crack tip.

About the regularities of Fatigue fracture and Fatigue strength due to the influence of asymmetry of the tension cycle
Mechanics, 2018Co-Authors: V. P. Bagmutov, A. A. Belov, V. I. Vodopyanov, O. V. KondratyevAbstract:The Fatigue Curves are obtained and the regulari-ties of the effect of the tensile cycle asymmetry in the range –2 ≤ R ≤ 0.5 on the length and position of the transi-tion section of the Fatigue Curve of steel 45 and titanium alloy PT-3V are investigated. Diagrams of limit amplitudes for the studied alloys are constructed. A method for calcu-lating the position and length of the transition stage of the Fatigue Curve is proposed.
