Method for quantifying defects in materials by microdensitometry of radiography films

Description

This report describes the principle of a method for quantifying defects on metal parts obtained by casting. It is based on the relation expressing the optical density of the image according to the thickness of the material. The three techniques used, to wit: gammagraphy, microdensitometry and data processing, are presented, as is the equipment used and the methodology adopted

Abstract (French)

Ce rapport expose le principe d'une methode de quantification des defauts sur des pieces metalliques obtenues par fonderie. Il repose sur la relation exprimant la densite optique du cliche en fonction de l'epaisseur de materiau. On presente les trois techniques mises en oeuvre: la gammagraphie, la microdensitometrie, le traitement informatique ainsi que l'equipement utilise et la methodologie adoptee
