abstract
Titanium alloys are used for hydraulic tubing in modern aircraft because of their excellent properties of specific strength as well as fatigue and corrosion resistance. However, the circumferential material properties of titanium tubing are relatively unknown. The interest in circumferential properties versus the axial properties stems from the strong texture development due to pilgering (Tuber Reducer) combined with the known anisotropy of oriented titanium microstructures. The goal of the current research was to gain a better understanding of these material properties as they relate to material specifications for industry applications. A unique test fixture was developed for cylindrical specimens. Force-displacement data was collected and used to calculate stress-strain relations. Because of the complex specimen geometry, a finite element model was developed to help relate the measured displacements to the actual stresses and strains. An iterative analysis of the data resulted in a estimate of Young’s Modulus of 18.7 x 106 psi, a yield stress of 130,000 psi and an ultimate strength of 143,000 psi for 0.5 inch diameter, Ti 3Al 2.5V tubing. The modulus was higher than expected, but these values were within the expected range for this particular titanium alloy and its processing history.
