Main Article Content
Abstract
Opracowanie zawiera syntetyczną informację o stanie badań dotyczących rozwoju magnetycznych nieniszczących metod diagnozowania materiałów poddanych działaniu promieniowania neutronowego. We wstępie podane zostały podstawowe informacje o skutkach napromieniowania stali oraz o próbie Charpyego. Opisano cztery metody magnetycznego badania próbek stosowanych do testów Charpyego: metodę pomiaru kolejnych pętli histerezy, metodę adaptacyjnego doboru warunków magnesowania, metodę pomiaru efektu Barkhausena oraz metodę jednoczesnego badania kilku wielkości magnetycznych. Dla każdej metody podano przykład jej zastosowania.
Magnetic methods of evaluation of neutron irradiated steels state
Abstract
Paper provides synthetic information about actual state of works on magnetic nondestructive methods proposed for evaluation of microstructure state of steels irradiated with neutrons. Introduction contains basic information about impact of neutrons on steel microstructure and about the Charpys test.Than four following methods are presented: minor loops metod, magnetic adaptive test metod (mAT), Barkhausen effect method and micro- magnetic multiparameter microstructure Analysis (3MA) method.
