摘要：

This paper proposes a new method to determine the Young's modulus by means of high temperature bending test. Considering that the global behaviour of the experimental device and the sample is purely elastic during the unload phase and by exploiting that the effects of the indentation under the contact are lower at the beginning of the unloading, it is proposed to deduce the Young's modulus from the slope of the unloading curve. It can be shown that the Young's modulus for different silicon carbide (SiC) based refractory materials obtained by using this method is in good agreement with results of others tests such as tensile test or ultrasonic measurement.
