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 کاملSpecial-Purpose Nickel Alloys
NICKEL-BASE ALLOYS have a number of unique properties, or combinations of properties, that allow them to be used in a variety of specialized applications. For example, the high resistivity (resistance to flow of electricity) and heat resistance of nickel-chromium alloys lead to their use as electric resistance heating elements. The soft magnetic properties of nickel-iron alloys are employed in ...
متن کاملCopper and Nickel Alloys Clad with Platinum and Its Alloys THE IMPORTANT INFLUENCE OF DIFFUSION
Cladding base metals with platinum or platinum alloys offers certain technical and economic advantages. In an earlier paper the mechanical properties of the metals to be joined were discussed. In this second paper it is shown that interdifi ion of the two materials being joined together must be considered, and that ifthe partners have different diffusion coefficients diffzculties can result dur...
متن کاملInterdiffusion in Composition Modulated Copper-nickel Thin Films
Interdiffusivities were measured in vapor-deposited Cu-Ni foils containing [ I l l ] composition modulations with wavelengths between 0.8 and 5 nm. The interdiffusivities in the range of 375-450 O C , measured from the decay rate of X-ray diffraction satellite intensities, were in good agreement with an extrapolation of existing high temperature data obtained with conventional diffusion specime...
متن کاملDIFFUSION AND REACTION WITHIN A SHAPED NICKEL PEROVSKITE CATALYST
Abstract : In this study, we prepared a LaNi0.3Al0.7O3 perovskite catalyst using a sol-gel related method (with prop ionic acid as a solvent) for use in the methane dry reforming reaction to produce synthesis gas. We defined the catalyst structure on the basis of X-ray diffraction analysis and measurements of the specific surface area and particle size distribution. The mixed oxide structure ...
