It is shown that temperature essentially influences the characteristics of elastic deformation waves, arising at development of internal defects. A group of materials are singled out, where temperature influence is insignificant, as well a group of materials, where dependence of AE properties on temperature is significant. The procedure and equipment were tired out in sections of process piping and high-temperature facilities of Odessa Port Plant (furnace, ammonia synthesis column, reforming reactor, transfer collector, etc.), on objects of TPP #5 and #6 of "Kievenergo" (bends of steam line of hot process overheating) Product Description popup.authors Бойчук Ольга Іванівна Висоцький Леонід Аврамович Волошкевич Ірина Георгіївна Грузд Анатолій Андрійович Дубик Тетяна Володимирівна Козаков Олександр Анатолійович Недосєка Анатолій Якович Недосєка Станіслав Анатолійович Овсієнко Марина Анатоліївна Смоголь Юрій Олексійович Федоряченко Віктор Сергійович Харченко Леонід Францевич Штефан Ярослав Олександрович Яременко Михайло Андрійович popup.nrat_date 2020-04-02 Close
