Abstract

Abstract

To systematically study the anisotropy of tensile and low cycle fatigue properties of commercial pure titanium, tensile and low cycle fatigue tests at room temperature were carried out along the rolling direction (RD), 30° to RD (RD-30°), 60° to RD (RD-60°) and transverse direction (TD). With the increase of sample angle, the yield strength and yield ratio increase, and the plasticity of the material decreases. The Hollomon model and Johnson-Cook model were used to predict the true stress-strain curve of commercial pure titanium, and it was found that the Hollomon model has higher prediction accuracy. Low cycle fatigue test results find that all samples show cyclic softening feature. The cyclic stress amplitude increases with the increase of sample angle, and the total strain energy density increases, resulting in a decreasing trend of fatigue life. The low cycle fatigue life of specimens with different orientations satisfies Manson- Coffin empirical relation.
