Abstract
An apparatus is described for the determination of Young's modulus from thin-rod resonance behavior. The apparatus differs from previously described equipment in that it is capable of operating at temperatures over 2000°C while providing a vacuum or an inert atmosphere around the sample. The transducers operate at ambient temperature and are loosely coupled to the specimen under test by fine tungsten wires. Provision is also made for optical measurement of the thermal expansion of the sample.
