Abstract Rotating discs are the vital part of many kinds of machineries. Usually they are operating at a relatively high angular velocity and temperature conditions. Accordingly in practice, the creep analysis is an essential necessity in the study of rotating discs. More recently the application of Functionally Graded Materials (FGMs) in the construction of rotating discs is the subject of many researches. These newly developed heterogeneous compounds enable the designer to manage the distribution of material properties and benefit their superior thermo-mechanical capacities. Apart from the patterns of material distribution, the shape of a disc is another factor which controls the stress field and consequently the deformation and life expectations. To study the effects of cross sectional profile, three different Aluminum-Silicon Carbide FGM discs with uniform, convergent and divergent cross section profiles are selected as the case studies. It is seen that there is a definite speed in which creep relaxation reduces considerably at the entirety of the disc. This important rotational speed is named the creep limit speed. Some case studies are represented to show the effects of disc profile upon the disc creep limit speeds.
