PROCEDURE FOR PRODUCTION OF METAL ITEM CONTAINING ANOTHER COMPONENT-ADDITIVE WITHOUT MELTING Russian patent published in 2010 - IPC B22F3/00 B22F9/18 

FIELD: metallurgy.

SUBSTANCE: invention refers to production of item out of alloy alloyed with alloying agent without melting. There is prepared a mixture of a non-metallic compound-precursor of basic metal and a non-metallic compound-precursor of an alloying element. Compounds-precursors are chemically reduced to metal alloy without melting. There is introduced one or more component-additive and metal alloy is compacted producing a packed metal item without melting. Also the component-additive is introduced during preparation of mixture or during chemical reduction, or upon chemical reduction. Additionally, an element, mixture of elements or a chemical compound are used as the component-additive. Notably, the component-additive is dissolved in a matrix or creates discrete phases in micro-structure of the alloy and is not reduced at the stage of chemical reduction.

EFFECT: facilitating production of items out of homogeneous alloy without melting its constituents causing oxidation; also composition of this alloy is impossible to produce by any other procedure.
