In many applications, FGM rotating discs are subjected to severe operating temperature and high rotational speeds. In such conditions the incidence of creep is inevitable. To study some aspects of this phenomenon, using the Sherby’s law the creep relaxation of a group of FGM rotating discs is modeled. Results show that even thought the temperature is uniform entirely, the stress variation leads to a phase transformation and so the creep mechanism is changed. In this paper the effect of this change of creep mechanism on the steady state creep behavior of FGM rotating discs made of Al-SiC is studied.
