“…Метод сканирующей контактной потенциометрии (СКП) на сегодняшний день изучен в полной мере и зарекомендовал себя как современный высокотехнологичный научный инструмент, обладающий уникальными особенностями. Применение метода СКП позволило решить ряд важных научных и практических задач [1][2][3]. Сегодня ГЛОБАЛЬНАЯ ЯДЕРНАЯ БЕЗОПАСНОСТЬ, № 1(46) 2023 данный метод выходит на стадию практического внедрения в промышленное производство и проходит заключительный этап экспериментальной и методической проверки на предприятиях атомной отрасли.…”

“…The SCP method have been used in tracking the martensitic formation in austenitic stainless steel in many joint experiments at IBR-2 research nuclear reactor in the Joint Institute for Nuclear Research (JINR) and results obtained were verified using thermal neutron diffraction method [13 -15]. Furthermore, the SCP method was used to study early formation and growth of embryonic fatigue cracks in metals [16]. A variety of research projects were conducted to study the performance of material such as lead-bismuth or lead to design a model for a real spallation target, the performance of neutronics, reactor physics and thermal hydraulics [17].…”

The issue of accurate identifying in advance structural nonhomogeneities of metals is one of the main factors in improving the manufacturing efficiency and safety during service. This paper illustrates the conventional uni-axial tensile test that is carried out on the diffuse and localized necking stages of dog-bone shape lead specimen. The scanning contact potentiometry method was used to locate the rupture zone. Infrared radiation was used to heat the specimen up to 40°C, in order to excite structural nonhomogeneities in the bulk of the tested specimen. It was found that the infrared radiation increases the predictable nonhomogeneity zone. A ductile rupture occurs in the same nonhomogeneity zone that was previously exactly identified using the scanning contact potentiometry method. The formed diffused necking was observed to initiate from the right where the rupture spread diagonally, at an angle of 70° between the tensile axis and the rupture plane. However, the angle between the tensile axis and the hexagonal singular reflex plane was 69°, which was slightly different from the rupture angle. Both results of the rupture angles of the tensile test and the SCP are relatively matching and diverse from the theoretical calculations. The results shown in this work highlight the importance and the efficiency of the experimental SCP method in prediction of the material failure behaviour.
