Fracture Toughness and Crack Resistance of Steam Pipeline Steel in Initial and Used States
Premature fracture of steam pipelines from 14MoV6 3 steel designed for 1000,000 h service life at 540°C has been studied. Test specimens are manufactured from steel in the initial state and after 117 h of operation. Application of the local approach to fracture and the metallographic analysis,...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Premature fracture of steam pipelines from
14MoV6 3 steel designed for 1000,000 h service
life at 540°C has been studied. Test specimens are
manufactured from steel in the initial state and after
117 h of operation. Application of the local approach
to fracture and the metallographic analysis,
in addition to classical methods (tensile, crack resistance,
and fatigue strength tests), provided a
more precise evaluation of steel properties degradation
due to elevated temperatures and stresses.
Urgency of further development of the local approach
to predicting material fracture after
long-term operation at high temperatures has been
substantiated. |
