Modelling the development of creep damage
Abstract
Many plant components are designed for long termoperation at high temperature, where they are subjectedto creep damage. Development of creep damage in the formof creep cavitation and cracking can be an important signof expended life, but has been relatively tedious tostudy in laboratory environment. Consequently, materialcharacteristic signature of creep damage has been mostlyobtained from service exposed material from the plant.This is inconvenient particularly for new materials forwhich no long term testing data or service experience isavailable.The paper describes the LICON approach to induceservice-like creep cavitation damage through multiaxialloading of feature specimens. Examples are shown anddiscussed for parent and welded 9% chromium steels P91,P92 and E911, as well as for dissimilar welds of 2¼Cr-1Mo(P22). The results demonstrate that unlike thetraditional uniaxial testing, the selected approach canproduce appropriate creep cavitation damage inhigh-ductility steels within a reasonable time tocharacterise new materials and to support in-serviceinspections.
