Sodium corrosion behavior of austenitic alloys and selective dissolution of chromium and nickel

Long-term corrosion of austenitic steels in flowing LBE at 400 °C and 10 −7 mass% dissolved oxygen in comparison with 450 and 550 °C

“…Before approximating corrosion data, one should identify the stages of corrosion process proceeding with different rate, i.e., typically faster at the initial stage and slower afterwards [22]. Another important issue is a choice of representative data.…”

Carburization behavior of AISI 316LN austenitic stainless steel – Experimental studies and modeling

“…For higher oxygen concentrations formation of ternary compounds of other transition metals has been observed [3]. Several reports are available on the preferential leaching of elements from structural materials in flowing sodium leading to changes in heat transport and mechanical properties [4][5][6].…”

Diffusion, Thermal Properties and Chemical Compatibilities of Select MAX Phases with Materials For Advanced Nuclear Systems

“…31 The weight loss in the annealed samples was also seen to be less than the 20% found in cold worked 316 stainless steel samples. 32,33 As with Suzuki et al 28 the σ-phase was found to nucleate near the exposed surfaces. An increase in micro-hardness -from 150±7 V H to 250±10 after exposure to Na -was also noted.…”
