PROCUREMENT OF METALLIC PRODUCTS BY RECONSTRUCTING OF NON-METALLIC JUNCTION-PREDECESSORS AND BY FUSION Russian patent published in 2008 - IPC C22B34/12 B22F9/18 

FIELD: metallurgy.

SUBSTANCE: invention pertains to procurement of metallic device; in particular, parts for gas turbines of the flying constructions made from titanium alloys. To produce such metallic devices, the following range of procedures must be brought into action. Firstly, one or several non-metallic junction-predecessors should be made ready, each containing metallic composition element therein. These need to be chemically restored to procure a multitude of initial metallic particles, preferably those whose size varies between 0.0254 mm to approximately 13 mm, which do not have to be melted down. After having been fused at a later stage, they will solidify. The melted and solidified metal can be used either as a casting metal product or can be transferred into a partially finished product (billet) to be processed additionally until it is ultimately ready. The invention permits to substantially reduce the frequency of chemical faults in a metal product.

EFFECT: procurement of metal products by means of reconstruction of non-metal junction-predecessors and by fusion with a view to decrease the frequency of any chemical faults.
