Inherent creep strength and long term creep strength properties of ferritic steels
Materials Science and Engineering: A, 1997Abstract Inherent creep strength is defined as a constant creep strength independent of time and microstructure. Sigmoidal inflection of a relation between stress and time to rupture is explainable in terms of a loss of creep strength followed by the advent of inherent creep strength. Although a large variation of short term creep rupture strength is

Creep-recovery of normal strength and high strength concrete
Construction and Building Materials, 2017Abstract The creep-recovery behavior of both normal and high strength concrete (HSC) under various load conditions has not been studied thoroughly. Although the use of HSC is long-established, rational creep-recovery prediction of HSC is still unavailable since current study just regards recovery deformation as a secondary result of creep experiments.

The creep strength of the Earth's mantle
Reviews of Geophysics, 1970In this paper we show that it is probable that at stresses greater than about 10−2 bar creep in the earth's mantle is caused by dislocation motion rather than by the mass transport of atoms through diffusion from one grain boundary to another. The latter process leads to Nabarro‐Herring creep.

Creep Failure Behavior of Creep-Strength Enhanced Ferritic Steels
Experience With Creep-Strength Enhanced Ferritic Steels and New and Emerging Computational Methods, 2004Creep-strength enhanced ferritic steels such as Gr.92, Gr.122, Gr.23 and Gr.91 have recently been introduced for power plant applications, and some of these have experienced creep failure in boiler tubes and thick wall components after several years of operation.

Long-term Creep Strength of Creep Strength Enhanced Ferritic Steels
2007Overestimation of long-term creep strength of creep strength enhanced ferritic steels is caused by inflection of a relation between stress and time to rupture. Creep rupture strength of those steels has been re-evaluated by a region splitting analysis and allowable tensile stress of some steels regulated in METI (Ministry of Economy, Trade and Industry)

Creep deformation properties of creep strength enhanced ferritic steels
Transactions of the Indian Institute of Metals, 2010Creep deformation properties of creep strength enhanced ferritic steels were investigated. Good linear relationships between creep strain vs. time and creep rate vs. time were observed within a transient stage in a double logarithmic plot. It was appropriately expressed by a power law rather than exponential law, logarithmic law and Blackburn’s ...

Creep Rupture Ductility of Creep Strength Enhanced Ferritic Steels
ASME 2010 Pressure Vessels and Piping Conference: Volume 6, Parts A and B, 2010Creep rupture strength and ductility of Creep Strength Enhanced Ferritic steels of Grades 23, 91, 92 and 122 was investigated with particular emphasis on remarkable drop in the long-term. Large difference in creep rupture strength and ductility was observed on three heats of Grade 23 steels. Remarkable drop of creep rupture strength in the long-term of

Predicting creep strengths and lifetimes of creep resistant engineering alloys
Metals and Materials International, 2018The physical basis for predicting the long-term creep strengths and lifetimes at application temperatures using creep parameters determined from short-term creep tests is investigated for complex creep resistant engineering alloys. It is shown that the seemingly unpredictable stress and temperature dependence of minimum creep rate of such alloys can be
