Description

Differential thermal and visual-polythermic analyses are used to study the phase diagram of a quaternary system of alkali- and alkaline-earth metal chlorides and nitrates. Five nonvariant points of eutectic and peritectic nature with melting temperatures of 158, 223, 206, 198 and 208 deg C respectively are found. The temperature dependence of corrosion rate is investigated for steels types Kh17N2, Kh18N9T, Kh18N10T, R6M5 at a 950 h exposure in eutectic mixture of a four-component system of LiNO3-NaCl-KCl-Sr(NO3)2 at 158-300 deg C

Abstract (Russian)

Дифференциально-термическим и визуально-политермическим методами анализа изучена диаграмма состояния четырехкомпонентной системы из хлоридов и нитратов щелочных и щелочно-земельных металлов. В системе найдены пять нонвариантных точек эвтектического и перитектического характера с температурами плавления 158, 223, 206, 198 и 208 град С соответственно. Изучена температурная зависимость скорости коррозии нержавеющих сталей Х17Н2, Х18Н9Т, Х18Н10Т, Р6М5 при 950-часовой выдержке в эвтектической смеси четырехкомпонентной системы LiNO3-NaCl-KCl-Sr(NO3)2 при 158-300 град C
