摘要： There are described powders comprising agglomerated nanocrystals of an electroactive alloy and oxygen. The main component of the alloy can be of nickel, cobalt, iron or mixtures thereof while the alloying element is one or more transition metals such as Mo, W, V, the alloy also including oxygen. Preferably the nanocrystals will be made of an alloy of nickel, molybdenum and oxygen. An electrode which is used by compacting the powders is also disclosed. Also disclosed, is a process for producing the powders by providing particles of nickel, cobalt and iron or oxides thereof with particles of at least one transition metal, (Mo, W, V) or oxides thereof and subjecting the particles to high energy mechanical alloying such as ball milling under conditions which include oxygen and for a sufficient period of time to produce a nanocrystalline alloy. Electrodes produced from these powders have an electrocatalytic activity for the hydrogen evolution which is comparable or higher than the electrodes which are presently used in the electrochemical industry. Moreover, these materials present an excellent chemical, electrochemical and mechanical stability. When use as a cathode the powders are useful in water electrolyzers, in chlor-alkali or the like cells.

摘要： Process for producing formed bodies with improved homogeneous properties, high resistance to oxidation and corrosion, great hardness and firmness, good mechanical workability, and high resistance to abrasion, made out of an initial power material which contains two elemental metals; or one or more alloys; or one or more elemental metals and one or more alloys; or a combination of one or more elemental metals and/or one or more alloys with one or more metalloids and/or one or more non-metallic substances, except for formed bodies made of NiTi, of Nb.sub.3 Sn, of stoichiometric, binary intermettalic yttrium-cobalt compounds and gadolinium-cobalt compounds, and of Ni.sub.60 Nb.sub.40, wherein the initial material, in metallic form or in the form of a hard material or a mixture thereof, is ground to a fine pulverized powder in a high-energy ball mill, and in which the fine powder is subsequently shaped into a formed body, comprising: conducting the fine pulverization of the powder in a dry, purified protective gas until it loses practically all of its crystalline properties, as proven by X-ray diffractometry, while employing a temperature during the milling process which is below the temperature at which crystallization first occurs, and employing a temperature, during the subsequent shaping which is below the temperature at which crystallization first occurs.

摘要： By the inventive method, an amorphous material in powder form can be produced, whereby at least two starting components in powder form are mechanically alloyed by means of a milling process so that a boron component which cannot be alloyed mechanically can nevertheless be alloyed. According to the invention, a boron component in powder form is admixed to the starting components; this powder mixture is subjected to the milling process, an amorphous alloying component being formed from the starting components with embedded or deposited fine particles of the boron components; and the mixture powder so produced is subjected to an annealing treatment below the crystallization temperature of the amorphous alloy component for diffusing the boron into the amorphous alloy component.
