Abstract

In order to study characteristics of material under conditions of creep and superplasticity, a technique is proposed for determining an index of speed sensitivity of steady creep stress. Method is based on analysis of relaxation curves, i.e. dependence of reaction forces of tested samples on time in process of stress relaxation due to creep developing in them. The example shows the use of this technique to determine creep of mullite-based ceramic composite samples.
