NDT Without Magnets

Southwest Research Institute engineers have developed multilayer thin films and combined them with magnetostrictive sensors to nondestructively detect and monitor defects in aircraft components. The technique, which requires no external magnets, has been successfully demonstrated to be capable of finding a crack in an A-10 aircraft test article and could in principle be applied to commercial craft and pipelines.
