EFFECT OF PLASTIC DEFORMATION ON THE PHASE COMPOSITION AND ELECTROMAGNETIC CHARACTERISTICS OF THE 321N AUSTENITIC STEEL (08Kh18N10T)

DOI: 10.17804/2410-9908.2022.6.095-106

The changes in the phase composition and electromagnetic properties of the 321N chromium-nickel austenitic steel under plastic deformation by uniaxial tension are studied. As strain increases from 0 to 0.37, the content of ferromagnetic α′-martensite in the steel increases monotonically to 60%. The electrical resistivity and the initial magnetic permeability increase monotonically by factors of 1,25 and 18, respectively. To monitor the strain state and the content of α'-martensite in products made of the 321N steel, it is preferable to use initial magnetic permeability rather than electrical resistance. The skin layer thickness of the deformed 321N steel for frequencies from 5 to 1000 kHz is calculated from the experimental values of initial magnetic permeability and electrical resistivity. Eddy current diagnostics of the state of the surface of products made of this steel, hardened by surface plastic deformation, is proposed to be performed at frequencies ranging between 100 and 200 kHz.

ВЛИЯНИЕ ПЛАСТИЧЕСКОЙ ДЕФОРМАЦИИ НА ФАЗОВЫЙ СОСТАВ И ЭЛЕКТРОМАГНИТНЫЕ ХАРАКТЕРИСТИКИ АУСТЕНИТНОЙ СТАЛИ МАРКИ 321Н (08Х18Н10Т)

Изучены закономерности изменения фазового состава и электромагнитных свойств хромоникелевой аустенитной стали марки 321Н при пластической деформации одноосным растяжением. Установлено, что с ростом степени деформации от 0 до 0,37 содержание ферромагнитного α′-мартенсита в исследованной стали монотонно возрастает до 60 %, при этом удельное электросопротивление и начальная магнитная проницаемость монотонно увеличиваются в 1,25 и 18 раз, соответственно. Сделан вывод о предпочтительном использовании начальной магнитной проницаемости, нежели электросопротивления, для контроля деформированного состояния изделий из стали 321Н и содержания в них α′-мартенсита. По экспериментальным значениям начальной магнитной проницаемости и удельного электрического сопротивления рассчитана толщина скин-слоя деформированной стали 321Н для частот от 5 до 1000 кГц. Предложено вихретоковую диагностику состояния поверхности изделий из этих сталей, упрочненных с помощью поверхностной пластической деформации, проводить на частотах 100…200 кГц.
