Abstract
The evaluation of residual stresses using ultrasound can be a very complex issue, because different material properties may effect the propagation of ultrasonic waves. Nevertheless, in the manufacturing of modern aero engines it is essential to benefit from the full potential of the employed materials. In this context, it is indispensable to test whether ultrasonic stress measurement is applicable for the highly developed nickel- and titanium-based alloys. This contribution contains basic investigations on the achievable measurement effect in samples made of Inconel IN718 and the Titanium alloy Ti 6-2-4-6. Furthermore, we give an overview over the principles of ultrasonic stress measurement using bulk and Rayleigh waves and present first results which are discussed with respect to texture effects and future work.
