Abstract

It is well known that the elastic constants of an isotropic solid (the bulk and shear moduli or the Young’s modulus and the Poisson’s ratio) can be determined ultrasonically when both longitudinal and shear wave velocities are measured. At high temperature, traditional ultrasonic techniques are difficult to apply because they require a coupling medium operating in the same temperature range. However, some results have been previously reported using momentary contact1–2, but the application remains difficult, especially for shear wave coupling, and above 1000°C. Obviously, an ultrasonic technique where ultrasound is generated and detected without contact can avoid such problems.
