Once cracks are found by inspection, the next
steps include making repair decisions and contemplating the risks to other
components. Yet the gap between discovering and solving the problem is often
complicated by the lack of information about the damage. Whether fatigue cracks,
corrosion cracks, manufacturing flaws, creep, graphitization, high temperature
hydrogen attack (HTHA), or another damage mode, each requires a different
solution—making its diagnosis critical for developing effective solutions. Field
replication can be used to nondestructively to identify crack types and damage
modes. This talk will demonstrate how field metallography can beused to bridge the gap between inspection
finding the problem and diagnosing the crack type needed to develop effective
solutions.
