After NDT inspection finds the presence of cracks, metallurgical analysis can explain how and why irregular cracks had formed. Metallurgical failure analysis uses lab-based equipment to provide details not visibly apparent. Such as proving the damage mechanism, identifying relevant environmental/loading factors and assess if a material condition had contributed to failure. Combined with the inspection findings, this information can help develop a comprehensive understanding of the damage, useful for developing strategies to resolve the issue.
In-situ metallography is a field, non-destructive technique which evaluates a component’s material condition. This method assesses the material structure of components on-site at accessible locations.
In-situ metallography can support inspection in the following applications:
- Plant shutdown inspection assessing for thermal degradation of boiler tubes, reactor shells and other parts which experience life-limiting service degradation.
- Examination of irregular NDT indications. Identify details regarding crack formation and surrounding material.
- Damage assessment in the event of a boiler/reactor failure. Provides information to ensure applied repairs remove damaged material.
