“…As one of the most widely used two-phase alloys, Ti6Al4V (by weight, named Ti64 or TC4), accounts for approximately half of the production of titanium alloys [7] and is an ideal material for use in the manufacture of engines and blades [8]. There are many factors which cause the various microstructures of Ti6Al4V, for example, alloy composition [9,10], processing technology, processing conditions [11][12][13], and so on. An alloy such as this structure is prone to fatigue and fracture failure when subjected to cyclic loading, while micro stress affects the crack propagation speed of the microstructure [14,15].…”

A mesoscopic mechanical model based on the Mori-Tanaka method and Eshelby’s inclusion theory was presented to investigate the uniform elastic deformation behavior of Ti6Al4V with β-Ti and α-Ti phases. In particular, elastic mechanics field equations of inclusion and matrix phases were established separately, and several crystal plane diffraction elastic constants were predicted under uniaxial loading in this model. The results demonstrated that diffracted crystal plane elastic constants diversified with the elastic stiffness of the composition phase. In consequence, elastic deformation of one particular phase is related to the constraint of the whole deformation of all the phases constituting the materials. In this work, diffracted crystal plane elastic constants corresponding to different phases exert a substantial role in the determination of stresses by diffraction methods. Several numerical simulation results were compared and discussed.
