Oxidation And Corrosion

Over the years, the study of the oxidation of nanoparticles of iron by transmission electron microscopy (TEM), Mossbauer spectroscopy and X-ray diffraction has established that nanoparticles of iron have a core-shell morphology in which the iron core is enclosed by shell of polycrystalline shell of ultrasmall γ-Fe2O3 and Fe3O4 crystallites. Recently, passivated nanoparticles of iron prepared by gas condensation of plasma evaporated vapor in Tianjin University exhibit remarkable resistance to further oxidation and corrosion in air and water. We have showed by TEM that these nanoparticles of iron are protected by a 4 nm epitaxial shell of γ-Fe2O3. The epitaxial orientation relationship, established by convergent beam electron diffraction from a nanoparticle, is as follows:The [001] diffraction pattern of the oxide is rotated by 45° about a cubic axis relative to that of iron.

Gallium Alloy

Two metal foils, one pure plutonium and the other being a solid solution of 6.5 a/o gallium In plutonium, were examined, in-situ, by X-ray diffraction techniques while under pressure. The purpose was to determine the compression and compressibility of these materials as a function of pressure and to identify the products of any transformation that may occur due to the action of applied pressures.

Phase and structural behaviour in the SmAlO3–TbAlO3system has been studied in a whole concentration range by means of laboratory X-ray diffraction,in situhigh temperature synchrotron powder diffraction and differential thermal analysis. Formation of the continuous solid solution Sm1−xTbxAlO3with the orthorhombic perovskite structure (space groupPbnm) has been established. Peculiarity of the investigated system is lattice parameter crossovers resulted in the existence of three regions with different relations of the lattice parameters. Based on the results obtained, as well as an available literature data for the “pure” SmAlO3and TbAlO3, a phase diagram of the pseudo-binary SmAlO3–TbAlO3system has been constructed.
