Abstract
This paper deals with nonlinear domains (second harmonic amplitude) in order to evaluate creep damage in titanium alloy. Creep damage has been observed in the form of microvoids at primary α/transformed β interface and the volume fraction of voids increases progressively with creep deformation. A good agreement between the experimental results and metallographic studies indicate the usefulness of the method for in-service evaluation of creep damage. A nonlinear ultrasonic technique was found to be significantly more sensitive for the assessment of creep damage.
