    Abstract: A process for producing a dispersed-oxide-containing alloy in which oxide particles of one or more additive metals are dispersed in a matrix metal. The process, which is for producing a dispersed-oxide-containing alloy, comprises (a) a step in which a powder or wire of an alloy comprising a matrix metal and one or more additive metals is produced, (b) a step in which the alloy powder or wire is introduced into a high-energy ball mill together with water and the contents are agitated to thereby oxidize the additive metals contained in the alloy powder with water and form dispersed particles, and (c) a step in which the alloy powder or wire after the oxidization is shaped and solidified. It is useful especially for the production of a dispersed-oxide-containing alloy in which the free energy of oxide formation of the matrix metal is higher than the standard free energy of formation of water and the free energy of oxide formation of the additive metals is lower than the standard free energy of formation of water.

    Abstract: Methods for sintering aluminum powder comprise providing aluminum powder and heating the aluminum powder in a nitrogen atmosphere containing a partial pressure of water vapor in the range of about 0.001 kPa to about 0.020 kPa to sinter the aluminum powder to a transverse rupture strength of at least about 13.8 MPa. The aluminum powder is not pressed together by a mechanical force that substantially deforms particles of said aluminum powder either prior to or during the step of heating. Articles comprising sintered aluminum powder. The sintered aluminum powder has a transverse rupture strength of at least about 13.8 MPa. The microstructure of the sintered aluminum powder contains no compositional concentration gradients indicative of the use of a sintering aid and no evidence of particle deformation having occurred by an application of a mechanical force prior to or during the sintering of the aluminum powder.

    Abstract: The invention concerns a low pressure process for the preparation of an iron-based, optionally alloyed powder comprising the steps of preparing a raw powder essentially consisting of iron and optionally at least one alloying element selected from the group consisting of chromium, manganese, copper, nickel, vanadium, niobium, boron, silicon, molybdenum and tungsten; charging a gas tight furnace with the powder in an essentially inert gas atmosphere and closing the furnace; increasing the furnace temperature; monitoring the increase of the formation of CO gas and evacuating gas from the furnace when a significant increase of the CO formation is observed and cooling the powder when the increase of the formation of CO gas diminishes.
