摘要：

The effect of temperature on cyclic creep parameters for refractory nickel alloys under asymmetric multicyclic loading was investigated. It is stated that a temperature rise causes a reduction in the life service of materials studied and a considerable increase in the cyclic creep rate. It is shown that the dependence of the steady-state cyclic creep rate on temperature is satisfactorily approximated by an exponential dependence in the Boltzmann form.
