Magnetic Method of Full-Scale Sample-Free Control of the Mechanical Properties of Ferromagnetic Steel Casing of Water-Moderated Reactors

摘要

A possibility of nondestructive control of the basic metal and welded joints of the clad casing of water-moderated reactors is shown. A method of full-scale sample-free control is developed on the base of combined method of kinetic hardness and magnetic method. The results of studying the magnetic and mechanical properties of casing steels in different states following irradiation and heat treatment are presented. It is shown that magnetic properties (and coercitivity in the first place) are sensitive to change in the material structure.
