STUDYING MECHANICAL AND THERMAL FATIGUE OF METALS BY THE INTERNAL FRICTION METHOD,
Abstract
The report represents the first effort of using the internal friction method to study mechanical and thermal fatigue of materials. For the beginning were selected pure metals: cadmium, zinc, aluminum and gold. Of the possible internal friction measuring methods for our purpose we used the low frequency method of torsional oscillations of low amplitude. The frequency of oscillations of the sample 100 mm long, profile 0.7 1 sq mm, was equal approximately to 1 c. As a measure of internal friction was used the logarithmic damping decrement, divided by pi. All measurements on the first pores were made w/o the use of vacuum i.e. in the air. (Author)
