Recent progress in creep-resistant bainitic, martensitic, and austenitic steels for high
efficiency coal-fired power plants is comprehensively reviewed with emphasis on long-term …

With the continuous development of science and technology, the increasingly severe service
environment makes people put forward higher requirements for the performance of alloy …

The creep behavior, deformation mechanisms, and the correlation between creep
deformation parameters and creep life have been investigated for Mod. 9Cr-1Mo steel (Gr …

Static recovery of tempered lath martensite microstructures of strength enhanced ferritic
steels has been investigated during very long-term aging up to 2× 104h at 650° C for 3 …

Creep behavior and degradation of subgrain structures and precipitates of Gr. 122 type x Cr-
2W-0.4 Mo-1Cu-VNb (x= 5, 7, 9, 10.5, and 12ápct) steels were evaluated during short-term …

This paper reports the short-term creep behaviour at elevated temperatures of a MarBN steel
variant. Creep tests were performed at three different temperatures (625° C, 650° C and …

The apparent activation energy for rupture life sometimes changes from a high value of short-
term creep region “H” to a low value of long-term creep region “L”. This change results in …

Boundary and sub-boundary hardening is shown to be the most important strengthening
mechanism for creep of martensitic 9Cr steel and is enhanced by fine dispersions of …

The cause of the breakdown of creep strength has been studied in Gr. 91 steel. The results
show that the contribution of the static recovery of subgrains to creep deformation causes the …

Creep rupture life and microstructural degradation have been studied in two heats of Gr. 91
steels. The coarsening of subgrains and precipitates, mainly M23C6 and MX, has been …
