Prospective high strength materials for loading at elevated temperatures used to be brittle at ambient temperatures. Contrary, the existing techniques to measure very low creep rates are convenient for ductile materials only. The aim of the project is twofold. On the practical level, it is the development of the techniques to measure very low creep rates on the prospective high strength materials with limited ductility, and the measurement of the basic creep characteristics of selected materials.On the theoretical level, the project should contribute to the current knowledge of the mechanisms of the viscous creep deformation.
