Abstract:
A method for producing articles from iridium metal nanopowder. This invention relates to the sphere of powder metallurgy and may find application in the production of different articles from iridium. Technically, the object of the invention is development of a new technology. To this aim a method is proposed for the production of articles from iridium based on use of chemically pure metal of not less than 99.99 purity, produced by electron-beam remelting, characterized in that the required material is turned to nanopowder of less than 100 nm dispersity from which seamless articles of various configuration are molded by their compacting at room temperature followed by baking, with the resulting isotropic structure featuring 100-300 nm grain size and strength characteristics being improved by 200-300%.
