An apparatus allowing the measurement in flexion, at low frequencies, of modulus and internal friction related to hysteresis and relaxation phenomena in metals has been developed. It is possible to use specimen with relatively high rigidity. The internal friction measurements are performed by the free decay method. The flexural oscillations are detected without contact by inductive transducers. The outer fiber strain range available is from 10-7 to 10-5 and the frequency range 0.2 to 10 Hz, between room temperature and 800 °C, under a vacuum of 10-6 torr.Un appareil de mesure du module d'élasticité et du frottement intérieur a été réalisé, afin d'étudier en flexion et à basse fréquence les effets d'hystérésis et de relaxation des métaux.
