Life Extension of Equipment Suffering Environmentally-Assisted Cracking: An Innovative Approach to Mitigation by Engineering of Materials in Service. Environmentally-assisted cracking (EAC) represents a serious threat to infrastructure exposed to caustic and chloride environments in process, marine, energy and chemical industries in Australia.

Environmentally-assisted cracking (EAC) represents a serious threat to infrastructure exposed to caustic and chloride environments in process, marine, energy and chemical industries in Australia. Despite extensive research, there is no consensus mechanism for EAC. This project will investigate a fresh approach to life extension of in-service equipment suffering EAC, by developing and testing a mitigation measure reasonably independent of the EAC mechanisms. The task includes development of a consolidated strategy based on: accurate determination of the fundamental parameters for crack propagation, and in-situ thermomechnical treatment for local manipulation of material at and ahead of crack-tip, in order to retard/stop crack propagation.Read moreRead less
