Abstract

L'invention concerne des procédés de contrôle de l'état déformé sous contrainte de différents articles faits de matières ferromagnétiques et paramagnétiques. Dans une première variante du procédé, sur la base des grandeurs des modules relatives à la différence des valeurs de tension du champ magnétique on détermine les coefficients Kinmoyen, Kinmin et Kinmax qui caractérisent les niveaux moyen, minimal et maximal des contraintes résiduelles ainsi que les coefficients g = Kinmin / Kinmax ou p = Kinmax / Kinmin. On compare les coefficients Kinmoyen, g ou p avec les coefficients correspondants admissibles Kinmoyen *, g* et p *, obtenus pour un échantillon d'un article valide, et sur la base de cette comparaison on juge de la validité de l'article contrôlé. Dans une deuxième variante, dans le dispositif contrôlé on détermine pour chaque canal de mesure et entre les canaux de mesure les valeurs des gradients de tension du champ magnétique. Sur cette base, pour chaque canal de mesure et entre les canaux de mesure on détermine l'indicateur magnétique de l'article mk de l'article et l'indicateur de la capacité de déformation du matériau de l'article dk= ∑mk, qui sont comparés aux valeurs limites correspondantes mlim et dlim. Sur la base de cette comparaison, on juge de la validité de l'article contrôlé et l'on détermine le temps limite de l'exploitation de l'article contrôlé.
