Intergranular Sulfur Attack in Nickel and Nickel-base Alloys
The phenomenology of intergranular sulfur attack in nickel and nickel-base alloys and the resulting embrittlement on post-exposure tensile testing was investigated. Using Ni 270 as a model material, specimens were exposed at temperatures between 450°C and 800°C to Fgous sulfur e vironments with sulfur partial pressures ranging from atm. to 10' B atm. Increasing exposure temperature and increasi...
متن کاملSulfur-impurity induced amorphization of nickel
Recent experimental and theoretical studies have shown an essential role of sulfur segregationinduced amorphization of crystalline nickel leading to its embrittlement at a critical sulfur concentration of 14%, but the atomistic mechanism of the amorphization remains unexplained. Here, molecular dynamics simulations reveal that the large steric size of sulfur impurity causes strong sulfur-sulfur...

متن کاملDetection of Reactive Sulfur Molecules ( S 6 , S 7 , S 9 , S ^ ) in Commercial Sulfur , in Sulfur Minerals , and in Sulfur Melts Slowly Cooled to 20 ° C [ 1 ]
Quantitative analysis by high-pressure liquid chromatography shows that all commercial samples of elemental sulfur besides S8 contain traces of S7 (up to 0.56%) and in some cases also S6, S9, and polymeric sulfur (S«,). Pure S8 can be obtained by recrystallization from CS2. Elemental sulfur minerals also quite often contain traces of S7 (up to 0.3%). Since neither irradiation by daylight at 20 ...
متن کاملEncapsulation of sulfur with thin-layered nickel-based hydroxides for long-cyclic lithium–sulfur cells
Elemental sulfur cathodes for lithium/sulfur cells are still in the stage of intensive research due to their unsatisfactory capacity retention and cyclability. The undesired capacity degradation upon cycling originates from gradual diffusion of lithium polysulfides out of the cathode region. To prevent losses of certain intermediate soluble species and extend lifespan of cells, the effective en...
