“…The use of electronic impedance (eddy current) measurements have been used to assess residual stress [14] and strain associated with the machining [15], hydrogen content in steel pipe [16][17][18], even thru organic coating [19], and in Zircaloy 4, under water [20]. With proper calibration and standardization a low frequency eddy current practice can be used as convenient and accurate nondestructive and non-contact method to measure the hydrogen in structural alloys.…”

The lattice of structural alloys possesses electronic characteristics which offer NDE predictions of potential failures in materials and structural assemblies. The atomic lattice represents a periodic potential which provide electronic wave descriptions that appear to be free. Any distortion in the periodic lattice (potentials) will achieve electronic and / or elastic interactions giving advance NDE waves tools possibility to assess stability of engineering materials at the atomic level during service life. Furthermore, the small dimensional defects (i.e. dislocations and interfaces) will produce steep potential gradients resulting in electronic and/or elastic physical properties changes that can be also measured. These collective potential and electronics signatures could be used as pre NDE lattice indications to produce awareness of potential degradations (i.e. susceptibility of fatigue, strain enhanced corrosion and cracking). The proper selection, utilization and assessment will increase both reliability and the NDE economics. A new approach to the next generation of nondestructive evaluations based on the electronic and elastic wave signals and analyses will be presented.
