“…Such a type of propagation yields a linear increase in penetration depth H, which is usually observed by other authors [10,12,18]. …”

“…As seen in §4.1, the dH dt À Á short time predicted can also be determined using relation (10) according to the Beaunier dissolution's model. By applying the factor k determined using the third method to this value, we obtain dH dt À Á long time predicted for the solution A which is also consistent with dH dt À Á short time experimental data (Table 5 and Fig.…”

“…However, Dunned, Whillock and co. [10][11][12][13] emphasized recently that the weight loss is hitherto normalized with respect to the nominal surface area of the test specimen, instead of to the actual area of the metal undergoing corrosion. The latter increases with time and reaches a constant value after the onset of stable grain dropping.…”

“…Several types of austenitic stainless steels are widely used as equipment materials in worldwide industrial PUREX plants [4][5][6][7]. They exhibit good corrosion resistance in hot nitric acid solutions owing to their passivity, which results from the formation of oxide films [8][9][10]. However, in the presence of fluoride ions in nitric acid solutions, the corrosion rates of stainless steels are greatly increased [11][12][13].…”
Section: Fluorex (Hybrid Process Of Fluoride Volatility and Solventmentioning
“…The corrosion rates were based on short-term tests. As the degradation of the dissolver vessel proceeds over time, the corrosion rate would be expected to increase until stabilizing at a high rate, as shown by long-term studies in nitric acid/fluoride environments [2,3]. The increase would be due to intergranular attack leading to grain dropout.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
