Abstract:In earlier N.P.L. work on the strength of carbon steels at high temperatures, steels showing ‘normal’ and ‘abnormal’ creep properties were assessed from tests extending to 1000 hours. Further results on the same steels indicate that the order of merit of these particular steels is not altered in tests extending to 100 000 hours. The rupture properties of carbon steels are reviewed in the light of the N.P.L. results and other published data. A wide range of strength properties is shown to exist. The pattern of… Show more
“…Under these circumstances Eq 1 can be looked upon as a mechanical equation of state and can be used to describe any plastic deformation process (tertiary creep excepted) with the aid of two stress-dependent parameters. Thus the purpose of creep research becomes equivalent to finding the explicit form of the Z (5) and et0 (5) relationships.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
