Electron microscopic analysis revealed that these defects are pores (cavities) and nonmetallic inclusions of different nature. The local chemical composition of inclusions and the metal matrix was studied to determine the possible causes of these defects formation.5481 Product Description popup.authors Майстренко Катерина Миколаївна Рослік Олександр Вадимович Тепла Ніна Михайлівна Чепіль Роман Володимирович popup.nrat_date 2020-04-02 Close
