Experimental resultsindicated that, at higher stress amplitude, the rupture life of cyclic creep is longerthan that of pure creep, and the rupture is mainly transgranular. At lower stressamplitude, the rupture life of cyclic creep is shorter than that of pure creep, andthe rupture is intergranular. Based on TEM observations of dislocation structuresand grain boundaries in ruptured specimens, the reason of cyclic strengthening andcyclic weakening at different stress amplitudes is considered to be: at higher stress,the damage in the interior of grains can be partly recovered during unloading inthe case of cyclic stress; while at lower stress, superposition of cyclic stress enhances the cavity formation and linkage at grain boundaries.
