"The goal of the project is to determine experimentally the high-temperature lifetime and cyclic creep data of Ni-base cast superalloy IN713LC under action of high tensile mean loads in high-cycle fatigue region. Attention will be devoted to the cyclic slip localization, changes of yly1 microstructure, crack initiation and early crack propagation. An attempt will be made to describe, explain and quantify the cyclic creep behaviour on the basis of the knowledge of loading rate and cyclic plasticity in the formation of unidirectional plastic strain. It is expected, that (i) basic experimental data characterizing the high-cycle fatigue lifetime at high mean stress and cyclic creep behaviour will be acquired (such data are not available in open literatu\u0159e), (ii) conclusions concerning the synergic effect of high-cycle fatigue loading and creep will be drawn, (iii) acquired experimental data will enable explanation of cyclic creep behaviour by means of a balance between an effectofthe stress"@en . .
