The application of magnetic structural phase analysis for the diagnostics of the State of a 08X18H10T Steel-Ct3 Steel composite material and its components that were subjected to plastic deformation

Investigation of the structure, phase composition and physical-mechanical characteristics of high-strength laminated materials which contain corrosion-resistant steels with high nitrogen content

“…However in comparison with early studied steel St3 [8], the peak field is shifted toward higher fields, what could be explained by the more alloyed 11CrNi4CuMoV steel. The peak fields (Fig.…”

“…In the initial state of 08Cr18Ni10Ti steel (Fig.4b) there is no if maximum on the field dependence due to the insufficient amount of a ferromagnetic phase in the material that is also confirmed by the X-ray diffraction analysis. However, when the strain increases, the -phase is formed [8,9] and at some value of εrol a peak begins to appear on the field dependence of the differential magnetic permeability. The dependence of the amount of strain induced -martensite on εrol for steel 08Cr18Ni10Ti is practically linear (Fig.…”

“…Accordingly, corrosionresistant steels are depleted by same elements at approximately the same distance. 4 for comparison shows the dependences μdif(H) for corrosion-resistant steel 08Cr18N10T [8], and 08Cr18N10, studied in this work. Figure 1b shows the dependences of μdif(H) for corrosion-resistant steel 08Cr18Ni10Ti.…”

Magnetic Evaluation of the Structural and Phase Changes in Individual Layers of Multilayer Products

“…Например, наиболее часто применяемые коррозионностойкие стали аустенитного класса об-ладают, как правило, деформационно-нестабильной структурой, в которой при силовом воз-действии могут протекать фазовые превращения с образованием в парамагнитной матрице ферромагнитных частиц -фазы, что приводит к снижению сопротивления межкристаллит-ной коррозии [22,23]. В связи с этим в процессе изготовления и эксплуатации необходимо ди-агностировать состояние деталей и элементов конструкций из подобных материалов [24,25]. Образцы для исследования вырезали из листовых сталей промышленной выплавки ма-рок Ст3 и 08Х18Н10Т (листы толщиной 3,9 мм и 1,9 мм соответственно).…”

Evaluating structural and phase changes in individual layers of multilayer products with the use of differential magnetic permeability

“…For example, the most frequently used corrosion resistant austenitic steels have, as a rule, a deformationally unstable structure, which may suffer phase transformations under force effect, with the formation of ferromagnetic -phase particles in the paramagnetic matrix, and this decreases resistance to intercrystalline corrosion [17,18]. In this connection, during manufacture and use, it is necessary to diagnose the condition of machine parts and structural components made of such materials [19,20].…”
