Abstract: A single and generalized prediction method of fracture toughness K IC transition curves of pressure vessel steels has been greatly desired by engineers in the petro-chemical and nuclear power ...

Abstract: The Cr-Mo steels widely used for pressure vessels have a potential for temper embrittlement. Therefore, embrittlement during long-term service is expected, and it leads to the decrease of the ...

Abstract: An urgent problem for nuclear power plants is to assess the structural integrity of the reactor pressure vessel under pressurized thermal shock. In order to estimate crack behavior under combined ...

Abstract: The applicability of AET to pressure vessels made of 2 1/4 Cr-1 Mo steel was studied by an extensive program which included: 1) a hydrostatic test of a test vessel with weld discontinuities, ...
