Description
The PUCOT (piezoelectric ultrasonic composite oscillator technique) has been used to measure the temperature dependence of dynamic Young's modulus of molybdenum disilicide (MoSi2) reinforced with 10, 30, and 50% volume fraction of pentatitanium trisilicide (Ti5Si3). The temperature ranges were room temperature to 600 C for the 30 and 50% specimens, and room temperature to 880 C for the 10% specimens. In all cases, the values of Young's modulus decreased linearly with increasing temperature, although at different rates. A graph of Young's modulus versus composition was used to estimate the value of Young's modulus for MoSi2. The value obtained (385 GPa) was in excellent agreement with the value of 388 GPa quoted in the literature
