EXPERIMENTAL DETERMINATION OF MAGNETIC ANTISOTROPY FIELD INDUCED BY STRESSES IN LOCAL ZONE OF LOW-CARBON STEEL PRODUCTS
Full text linkFields of induced magnetic anisotropy and average values of mechanical stresses in pre-plastically deformed steel plates of St-20 steel were experimentally determined using the original primary transducer. It is established that at a relative elongation of the sample of about 10%, the field of induced magnetic anisotropy has a maximum.Работа выполнена в рамках государственного задания ФАНО России (тема «Диагностика», № г.р. 01201463329) при финансовой поддержке РФФИ (проект № 16-58-00027 Бел_а)
EFFECTS OF A PEARLITE MORPHOLOGY AND A PLASTIC DEFORMATION ON THE MAGNETIC PROPERTIES AND A RESIDUAL STRESS OF THE EUTECTOID STEEL
Full text linkThe comparison of the magnetic properties of the deformed and undeformed U8 steel samples with different cementite forms and sizes was carried out. The main changes of mag-netic properties were found for the sample with nodular cementite.Исследование выполнено в рамках государственного задания МИНОБРНАУКИ России (тема «Диагностика», №АААА-А18-118020690196-3) при финансовой поддержке РФФИ в рамках научного проекта № 20-32-90139
