Abstract
In this study, the degree of creep damages on the weldment accelerated creep degradation was nondestructively evaluated by replica method. The frequency of creep cavities occurrence has been observed highly at the intercritical HAZ. The life fraction of weldment damaged by creep has shown from 0.25(damage grade: 2) to 0.75(damage grade: 4) when it reptured. The degree of creep damages is considered to be evaluated by the metallographic replica method which is one of nondestructive evaluation methods.
