摘要：
At the Institute of Materials Science and Engineering of the University Kaiserslautern an ultrasonic testing facility was developed to perform fatigue tests in the VHCF regime. The individual design of the ultrasonic testing facility allows to control the process parameters and to measure relevant data with a frequency of up to 500 kHz in reasonable time. This permits a high-resolution measurement of the ultrasonic oscillation and the dissipated energy as well as a determination of microstructural reactions inside the specimens. With the described ultrasonic testing facility constant amplitude tests and load increase tests were carried out with the alloy Ti6A14V. The results show that the innovative test and measuring techniques are best suited to describe the fatigue behaviour of Ti6A14V. Additionally, for the first time high resolution 3D scanning laser vibro-metry were carried out to determine the oscillation behaviour of specimens under ultrasonic cyclic load.
