dc.description.abstractTemperature of burned gases is a key parameter in output works of gas turbines. Nevertheless, high temperatures cause metallurgical problems in the turbine parts, specially the blades. Hence, ZrB2 as an ultra-high temperature ceramic (UHTC) with a melting point of 3246 degrees C, considerable high-temperature strength and relatively high thermal conductivity can be a proper candidate for manufacturing of gas turbine parts. In the present work, heat transfer and related thermal stresses of a gas turbine stator blade made of ZrB2 ceramic is investigated numerically by means of Comsol Multiphysics software and the obtained data are compared with M152 (UNS S64152) alloy. The results showed that ZrB2 has more uniform temperature distribution than M152, which is corresponded to its lower thermal gradient. Due to its lower thermal expansion coefficient, ZrB2 showed lower total displacement than M152 which is an important parameter in blade performance. Also, the Von Mises stress of ZrB2 showed higher value than M152.
