POSSIBILITY OF NONDESTRUCTIVE TESTING OF AUSTENITIC CHROMIUM-NICKEL STEELS’ PHASE COMPOSITION USING ELECTRICAL RESISTIVITY

Studies of the relationship between electrical resistivity and the phase composition of austenitic chromium-nickel steels were carried out. Correlation was found between electrical resistivity and ferrite or deformation martensite content in the original or deformed samples, correspondingly.Работа выполнена в рамках государственного задания МИНОБРНАУКИ России (тема «Диагностика», № 122021000030-1)

Application of Modern Methods and Techiques for Phase Composition Evaluation of Austenitic-Ferritic Steels

Review of methods and techniques, used for phase composition control of austenitic-ferritic steels was performed. Some limitations of ferrite content evaluation with different devices are shown. New methods of phase composition control of these steels for wide range of ferrite content are proposed.Работа выполнена в рамках государственного задания ФАНО России (тема «Диагностика», № АААА-А18-118020690196-3)

RESEARCH OF TEXTURE-PHASE TRANSFORMATION IN AUSTENITIC CHROMIUM-NICKEL STEELS BY MEANS OF MAGNETIC NON-DESTRUCTIVE TESTING

Research of samples made of austenitic steels with deformation-induced martensite is performed. Measurements of relative magnetic permeability in crossing directions showed different results which proved presence of texture in steel.Работа выполнена в рамках государственного задания ФАНО России (тема «Диагностика», № АААА-А18-118020690196-3)
