Abstract: A method for preparing flat foils having a high density includes the steps of mixing a powdered material with a binder to form a green sheet. The green sheet is exposed to a high intensity radiative source adapted to emit radiation of wavelengths corresponding to an absorption spectrum of the powdered material. The surface of the green sheet is heated while a lower sub-surface temperature is maintained. An apparatus for preparing a foil from a green sheet using a radiation source is also disclosed.

Abstract: A method for making a radioactive article such as wire, includes the steps of providing a metal article having a first shape, such a cylinder, that is either radioactive itself or can be converted to a second, radioactive isotope by irradiation; melting the metal article one or more times; optionally adding an alloying metal to the molten metal in order to enhance ductility or other properties; placing the metal article having the first shape (e.g., cylindrical) into a cavity in the interior of an extrusion body (e.g.

Abstract: Novel wear-resistant, anti-galling, cobalt-free hardfacing iron based alloys are provided which are useful for construction of plant or manufacturing facility components exposed to aggressive environments. The alloys are particularly useful to construct components used in the cooling systems of nuclear power plants.

Abstract: Solid solutions of molybdenum and tungsten having molybdenum to tungsten atom ratios between about 1:1 and about 10:1 are produced by heating a mechanically milled mixture of a molybdenum oxide and tungsten oxide to a temperature between about 1000.degree. C. and about 1300.degree. C. at a rate of at least about 20.degree. C. per minute in a hydrogen-containing atmosphere and holding at temperature to reduce the oxides of molybdenum and tungsten and to provide a homogeneous solid solution of molybdenum and tungsten. The homogeneous solid solution is mixed with a stoichiometric excess of carbon and heated to a temperature between about 1200.degree. C. and about 1800.degree. C. under a protective atmosphere to react the carbon with the alloy powder to form a solid solution of hexagonal monocarbides.
