Abstract
The elastic modulus of near β and β titanium alloys was measured by nano-indentation and ultrasonic techniques. The data obtained from both the experiments were analyzed and compared with each other. The effects of composition and heat treatment on elastic modulus of the material are discussed. The elastic modulus of β Ti–35Nb–5.7Ta–7.2Zr (TNTZ) was found to be half of the elastic modulus of the titanium. Near β Ti–13Zr–13Nb (TZN) alloy hot worked at 800 °C and solution treated at 800 °C followed by water quenching also showed low elastic modulus value. The accuracy of these two elastic modulus measurement techniques is discussed in terms of microstructures.
