THE APPARATUS FOR MEASUREMENT OF YOUNG’S MODULU OF CERAMICS AT ELEVATED TEMPERATURES
Abstract
The construction of a laboratory-made fully automated resonant apparatus for the modulated force thermomechanical analysis (mf-TMA) is described. The measurement is based on the impulse excitation technique (IET). The apparatus is able to provide the measurements of the resonant frequency, which is a base for determination of Young’s modulus, sound velocity and internal damping during heating up to 1200 °C. An expanded relative uncertainty of the Young’s modulus determination at elevated temperatures is 1.1 %.
