Description
Summary:The method of basic diagrams was used to analyze > 200 creep-rupture diagrams obtained in long-term experiments (100 000 h or more). The analysis of known experimental data and the prediction of creep rupture based on the departure of some portions of experimental diagrams from the corresponding portions of basic ones offers strong possibilities for increasing the accuracy and reliablity of predictions. Kh18N10T steel is discussed, and data is given for some Cr-Mo-V, Cr-Mo and Cr-Ni-Ti high temperature steels.
