The anomalous dispersion effects, which arise when the energy of the incident X-ray beam is close to the absorption edge of zinc, are used to monitor the variation of the small-angle scattering of Zn-rich G.P. zones. Quantitative measurements with a synchrotron radiation source give the f' variation with a good accuracy and show the feasability of the method for studying more complex metallurgical systems.On utilise l'effet anomal qui se produit au voisinage du seuil du zinc pour suivre la variation de la diffusion aux petits angles donnée par des zones de Guinier-Preston riches en zinc. Des mesures quantitatives effectuées avec le rayonnement synchrotron donnent la variation de f' avec une bonne précision et montrent ainsi la faisabilité d...
