Comparison of strength characteristics of heat resisting materials under active tension and constant load

Strength characteristics of heat resisting materials (steel 12Kh1MF) obtained during short-term active tension with constant deformation rate are shown to be used for plotting curves of a long-term strength on small temporal basis. For this purpose a graph was suggested to be marked with the points whose coordinates corresponded to a value of a spontaneously measured active deformation time to failure of a sample with the respective equivalent strains determined from deformation curves by a calculation method
