Abstract
Abstract A method of production of an alloy wherein powders containing the constituents thereof are intimately mixed, the mixture thus obtained being charged inside a casing, closed with a cover recessed on the face facing the interior of the casing fitted with a bore, the assembly thus obtained being subjected to one compression operation, the bore in the cover being plugged, after which the compressed assembly is subjected to an extrusion operation, the outer layer being subsequently removed by a machining operation. The cover is produced from a metal which at extrusion temperature suffers less deformation than the mixture inside the casing.

A method for the production of an alloy, comprising mixing powders of the constituents used for making up the alloy, charging the resulting mixture inside a container having the shape of a tray, subjecting said container to a rotation offset within its own plane, charging said mixture from said container inside a metal casing, closing said casing with a cover provided with a bore said cover being made from a metal which at the temperature of the extrusion is subject to less deformation than the mixture charged inside the casing, forcing said cover into said casing in order to compress said mixture, closing said bore in said cover with a plug, placing the closed casing in an extrusion chamber with the cover remote from the die opening of the chamber, subjecting said closed casing to an extrusion operation in order to produce an extruded product the outer layer of which is made up of the metal of the casing, and removing said outer layer.
