Purpose: The purpose of this paper is description of the creep resistant steels low cycle fatigue life under gradual loading. Design/methodology/approach: The low cycle test at high temperatures have been performed. This kind of fatigue is typical for materials worked at high temperature conditions. Findings: The model has been worked out in the work, which considers an influence of the loading sequence on the fatigue life of steels worked at a high temperature under mechanical loading. Research limitations/implications: The paper presents results of the part of research connected with methods of life prediction of materials worked under mechanical and thermal loading. From many aspects connected with the life criteria the work has been focused on the problem of the influence of the loading sequence on the fatigue life. This problem should be examined with many others when the durability of high temperature component is considered. Practical implications: The results of low-cycle fatigue could be useful in problems of quality assessment of the examined steels and in analysis of the influence of the character of loading on the material behaviour. Originality/value: The paper presents the own new description of the low cycle fatigue life of steels under gradual loading. The own new fatigue life criterion has been proposed.
