发明名称 METHODS AND SYSTEMS FOR DETECTING NONUNIFORMITIES IN A MATERIAL, COMPONENT, OR STRUCTURE
摘要 Methods of detecting non-uniformities in a material are described. Such methods can comprise inducing changes in strain state or changing the magnetic moment of a material and measuring magnetic flux leakage that is synchronous with the changes in strain state or magnetic moment, while simultaneously applying an external magnetic field to control the relative magnitude of the magnetic flux leakage.
