Effect of Compound Energy-Field with Temperature and Ultrasonic Vibration on Mechanical Properties of TC2 Titanium Alloy

Abstract

To solve the problem of the poor plasticity and to meet the requirements of high temperature for forming titanium alloy, mechanical properties of TC2 titanium alloy under the compound energy-field (CEF) with temperature and ultrasonic vibration were studied. The effects of CEF on tensile force, elongation, microstructure and fractography of the TC2 titanium alloy were compared and analyzed. The results show that, under the same thermal conditions, the deformation resistance of TC2 titanium alloy decreases with the increase of ultrasonic vibration energy. The formability is also improved correspondingly due to the input of ultrasonic vibration energy and its influence on the microstructure of the material. However, when the ultrasonic vibration energy is larger, the fatigue fracture will also appear, which reduces its formability.
