- ПубликацияТолько метаданныеApplying Scanning Contact Potentiometry for Monitoring Incipient Cracks in Steels(2019) Surin, V. I.; Polskij, V. I.; Osintsev, A. V.; Dzhumaev, P. S.; Сурин, Виталий Иванович; Польский, Валерий Игоревич; Осинцев, Андрей Вениаминович; Джумаев, Павел Сергеевич© 2019, Pleiades Publishing, Ltd. The processes of formation and growth of an incipient crack in EI847 steel have been studied by uniaxial constant-load tension testing on an INSTRON-5982 tensile testing machine using scanning contact potentiometry. The nucleus was detected at the sample surface within the yield strength domain and was stably monitored based on the readings of apparatus under higher loads until the moment of destruction.
- ПубликацияТолько метаданныеExperimental investigation of the failure of steel AISI 316 by the methods of structural analyses(2019) AbuGhazal, A. A.; Dzhumaev, P. S.; Osintsev, A. V.; Polsky, V. I.; Surin, V. I.; Джумаев, Павел Сергеевич; Осинцев, Андрей Вениаминович; Польский, Валерий Игоревич; Сурин, Виталий ИвановичThe failure of reactor steel AISI 316 under tension was investigated by structural analysis and scanning contact potentiometry (SCP). In real time surface potentiograms were plotted by the change of which the growth of crack nucleus was tracked from its initiation till the stage of cup fracture formation. The nucleus of the microscopic crack on the potentiogram was first detected at the end of the next to the last cycle of testing at a load of 525 MPa in the yield region and then was persistently reproduced on potentiograms in subsequent tests up to the failure. The most noticeable changes in the parameters of dynamic waviness and roughness occurred at the moments of sharp crack growth. Using the results of the SCP method, three main stages of crack development were identified. In the first one, under loads corresponding to the conditional yield point, a nucleus was formed in the region of the maximum tangential stresses. This region of localization arises as a result of macroscopic loss of stability due to the significant mechanical energy accumulation by the system, which leads to an increase in the magnitudes of the plastic strain fluctuations. The second stage, the one of a progressive growth of the crack nucleus, is the longest in time and lasts from the moment of detection of the nucleus to the sample failure. The amplitude of the electrical potentials in the central part of the sample increased with the rise in intensity of the applied load which is associated with an increase in the inhomogeneity of the internal stress field around the nucleus, as well as the accelerating creep process and the growth of plastic strain in this region. At the pre-failure stage in the hardened surface layer, a macro-groove appears in the form of a standing deformation wave along the fracture line. Under the microscope, shear strain bands on the sample surface are also visible.

N.; Osintsev, A. V.; Dzhumaev, P. S.; Polskiy, V. I.; Sergeev, K. L.; Shchekin, A. S.; Быковский, Дмитрий Петрович; Ишкиняев, Эмиль Дамирович; Петровский, Анатолий Николаевич; Осинцев, Андрей Вениаминович; Джумаев, Павел Сергеевич; Польский, Валерий Игоревич; Щекин, Александр Сергеевич© Published under licence by IOP Publishing Ltd.The microstructure of 316L stainless steel obtained by layer-by-layer direct metal laser deposition is reviewed. Mechanical tests of the samples were performed in accordance with GOST 1497-84. Studies show that changes in power of laser radiation to grow parts lead to changes in their mechanical properties. The research shows dependencies between the strength characteristics of materials and the power of laser radiation. Causes of the forementioned changes are studied through the analysis of the microstructure. Nanosized inclusions of spherical shape were found in the process of studying the microstructure of materials. A study in the nature of the formation of these inclusions and their effect on the properties of the obtained material was performed.

I.; Петровский, Анатолий Николаевич; Осинцев, Андрей Вениаминович; Джумаев, Павел Сергеевич; Польский, Валерий Игоревич© Published under licence by IOP Publishing Ltd.The paper considers the possibility of using laser milling technology for precision processing of ceramic samples from pre-sintered and sintered ceramics zirconia and lithium disilicate. To find the best radiation source were compared different lasers. To find highest removal rate with acceptable accuracy was studied influence laser and scanning system parameters on ceramics. Accuracy problem of laser milling was considered. Examples of surfaces of prostheses were made.
