Recent developments in digital signal analysis have allowed substantial progress in the field of impulse excitation techniques (IET), i.e. the mechanical-spectroscopic analysis of 'impulse excited' resonant vibrations. The new IET-devices determine several impulse excited resonance frequencies simultaneously. Upon each single impulse excitation, the internal friction corresponding to each of the analysed frequencies is deduced from the exponential decay of the vibration amplitude. In this paper, data obtained with a resonance frequency and dumping analyser (RFDA) which is linked to two furnaces, are presented. One of the furnaces can reach temperatures up to 1100 degrees C in air. This furnace was used to characterise phase transformations ...
