Sažetak
The characteristics of low-cycle strength and cyclic creep of a Mo-30%W-NbC-C alloy produced by powder metallurgy are studied at temperatures of 1770, 2020, and 2270 K. In this temperature range the unified dependence of the cyclic steady-state creep rate on the ratio of the equivalent stress to the yield strength of the material at a certain temperature is obtained. Moreover, the generalized curve of the low-cycle strength of the alloy is constructed. The cyclic character of the loading accelerates the processes of directed plastic deformation and fracture in the powder alloy by a factor of 1, 5 -7 as compared to the corresponding long-term static loading, with the curves of cyclic and static creep being qualitatively similar.
