Bj. Smith et al., HIGH-TEMPERATURE CORROSION-FATIGUE (CIRCUMFERENTIAL) CRACKING LIFE EVALUATION PROCEDURE FOR LOW-ALLOY (CR-MO) BOILER TUBE STEELS, Materials characterization, 34(2), 1995, pp. 81-86
A laboratory simulation procedure for reproducing high-temperature cra
cks found in coal-fired boiler tubes was developed. The procedure desi
gn was based on an intergranular corrosion/thermal stress interactive
initiation mechanism and an environmentally assisted fatigue crack pro
pagation mechanism. Simulation results show the potential of this proc
edure as both an evaluation tool for material solutions to the problem
and a life estimation procedure for new boiler tube surface modificat
ions.
