Utilisation des SQUID pour l'évaluation non destructive : développements récents.

Recent progress in the use of SQUIDS for non-destructive evaluation.

Auteurs : DONALDSON G. B., CARR C.

Résumé

The authors report on recent developments in the use of SQUID (Superconducting Quantum Interference Device) sensors for the magnetic detection of a variety of surface-breaking and deep-lying flaws in metals, including iron, steel, aluminium and titanium. The methods employed are first magnetometry, in which the defect is polarised by a magnetic field and the induced dipole moment detected by a SQUID, and secondly galvanometry in which the flaws distort the flow of eddy currents excited in the specimen and the SQUID measures the subsequent distortion of the magnetic field generated by these currents. These developments have allowed non-destructive evaluation to be extended to a number of problems of concern, including the detection of deep lying defects in engineering structures such as pipe lines and reactor vessels, and in aircraft structures and components.
