Abstract: Powder metallurgy techniques are often used in the fabrication of finished and semi-finished articles. At the CEA, a cold followed by a hot isostatic pressing method is used to produce solid ...

Abstract: In order to validate the long-term behavior of fast breeder reactor steam generator tubes, a creep test monitoring program has been undertaken. A series of over one hundred tests was performed ...

Abstract: The high-temperature design codes are presently considering the use of stress reduction factors for designing welded structures submitted to creep. These reduction factors are derived from creep ...

Abstract: In order to get a better understanding of the role of various parameters on the creep collapse phenomenon of long circular tubes, an experimental and numerical program has been undertaken. It ...

Abstract: The local approach criterion of fracture mechanics, initially developed by Beremin for brittle cleavage fracture, is applied here to A508 class 3 low-alloy ferritic steel. This criterion, based ...
