On the one hand, the completion of the task is wanted by a kind of preformed material as described in claim 1 and by such as right
Its manufacturing method described in asking 5 or 6 is realized.Advantageous modification of the invention is described in other claims.Accordingly,
The preformed material containing manganese for the powder metallurgically manufacturing for being preferably the magnesium alloy without aluminium for manufacturing light metal alloy has consisting of,
It is with formula Mn100-x-y-zAxByCzStatement, wherein A is at least one in elemental cerium (Ce), elements La (La) or Ce mixed metal
Kind, B is scandium (Sc), and C is zirconium (Zr), and the compositing range of x, y, z be the weight of 0≤x≤37 weight of %, 0≤y≤4 % and 0≤
The weight of z≤9 %.
The preformed material can be constituted in the form of without the wire of involucrum or leather shell or the wire of more mutual twistings.
In the form of for manufacturing the preformed material that light metal alloy is preferably magnesium alloy manufacture wire can by two ways into
Row.
First, in the first step, the metal component of the preformed material passes through gas atomization either individually or in combination and is turned
It turns to powdered.In the second step, as expected preformed material composition is mixed the ingredient of powdered, and in third
It is packed into step in compacting cylinder and material pin is shaped to by hot isostatic pressing compacting.In hot isostatic pressing compacting, compacting
Cylinder is loaded into heatable pressure boiler, and herein, powder is then " up to 2000 DEG C and the preferably lower than ingredient include
It the temperature of the solidus temperature of peak melting point " and is compacted in protective gas 100 to 200MPa pressure.The air pressure because
This acts on the material pin from all quarter, so that material pin obtains isotropic behavior.
By air pressure in all side actions and high temperature, the creep process of diffusion-controlled works, this creep process causes
The compacting of material pin material.
In four steps, the material pin so obtained is deformed into wire by the extruder with perforation former, with
Wire is rolled afterwards.Perforation former can have one or more perforation, so as to by squeezing while manufacturing more gold
Belong to silk.
Secondly, following melts can be manufactured by the ingredient of preformed material, it is then act through misty course of injection and is formed as spraying
Penetrate the material pin of densification.The material pin of injection densification is equally with isotropic behavior and by the extruding with perforation former
Machine is deformed at least one wire.
