The preliminary measurements that we have shown here indicate that thermography is the appropriate NDE method for inspecting FeAl green sheet. Modern instrumentation allows single-sided, non-contact, on-line inspection, with sensitivity to the green sheet flaws of interest, and at rates that allow for 100% coverage. Based on this preliminary data a prototype inspection system has been developed to study the details of green sheet flaw morphology. Future work will focus on the understanding of flaw development throughout the various processing steps. The ultimate goal of the research will be to provide specifications for on-line integration of an inspection system.
