Sources of high creep resistance of modern high-chromium martensitic steels

In this work, the sources of the high creep resistance of martensitic steels containing 9% Cr were considered based on the results of studying the evolution of the dislocation structure of martensite in P92-type steel in creep at 650°C. The steel structure after tempering was characterized by significant elastic microstrains of the crystal lattice, which were produced by dislocations of the same sign and long-range stresses from the dislocation...
