Prediction of the long-term strength of pipeline metal taking account of crack development under creep conditions

A procedure which makes it possible to predict the long-term strength of smooth specimens from the endurance and nominal breaking of cylindrical specimens with a sharp notch without exceeding the working temperature is substantiated theoretically and proved by experiment for pipeline steels (12KhlMF...

Description
Summary:A procedure which makes it possible to predict the long-term strength of smooth specimens from the endurance and nominal breaking of cylindrical specimens with a sharp notch without exceeding the working temperature is substantiated theoretically and proved by experiment for pipeline steels (12KhlMF, 15KhlMlFL, 20KhMFL). This prediction makes it possible to reveal more reliably the breaking point on the long-term strength curve and to provide reliable results for evaluating high-temperature strength with much shorter tests.
