Distinctive features of fatigue crack growth in 14Mo V63 pipe steel after service

We study the influence of technological parameters of operation of the bends of steam pipelines made of 14Mo V63 steel on the kinetic characteristics of fatigue crack growth. We show that an increase in the steam pressure in the pipeline determining the stress-strain state of the pipe wall promotes...
