| Citation: | Reasons for crack nucleation in welded joints of main gas-pipelines after a long-term operation / P. O. Maruschak [et al.] // IOP Conference Series: Materials Science and Engineering. — 2017. — Vol. 177 : Mechanical Engineering, Automation and Control Systems (MEACS 2016) : International Conference, October 27–29, 2016, Tomsk, Russia : [proceedings]. — [012114, 4 p.]. |
| Abstract: | A crack of operational origin in the welded joint of the main gas pipeline is analyzed. The reasons for its nucleation and impact on technological microdefects that were formed earlier during the welding are found. Micromechanisms and stages of nucleation and propagation of the crack are investigated. |
