Towards the correlation of fracture toughness in an ex-service power generating rotor

Journal Article


Abstract

  • This work presents preliminary results from a project aimed at deriving fracture toughness correlations for an improved assessment of the structural integrity and remaining life of low alloy steel pressure equipment where susceptibility to temper embrittlement is a consideration. Room temperature K(Ic) tests, Charpy tests and small punch tests were performed on samples extracted from three different locations of a 1Cr-1Mo-0.25V wt% ex-service (136,000 h) turbine rotor in the ex-service condition. Proposed correlations for two mechanical methods are presented and discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
