Definitions
- the invention relates to a powder metallurgically produced, manganese-containing
- Starting material for producing a light metal alloy preferably one
- Magnesium alloy and a process for its preparation and its use Magnesium alloy and a process for its preparation and its use.
- the production of alloys is usually carried out by alloying a
- Main component Pure metal
- minor components additives.
- this is done by introducing the alloying additives in the form of ingots or ingots into the liquid melt of the pure metal.
- ingots or ingots Due to their compact size, ingots or ingots have the disadvantage that they, if they have a higher melting point, only incomplete
- Inclusions or mono-elemental regions called chunks of one of the alloy metals may later lead to failures in the further processing of the alloy material.
- melts are the wire injection by means of filler wire, with an outer sheath of metal and a filler, wherein the
- Filler material one or more powdered metals or granular metals and is formed as a wire without sheath.
- Cored wires for the metallurgical treatment of melts are well known. This treatment is characterized in that, in contrast to other known methods, the addition amount of the alloying additives to the melt can be accurately controlled.
- the sheath of the cored wire serves to powder or granular To transport alloy additives via a wire injection device or to supply the melt.
- a wire injection device is known for example from DE 37 12 619 AI.
- Cored wires for the treatment of melts by wire injection are known, for example, from DE 199 16 235 A1, DE 19916234 A1, DE 100 65 914 A1, DE 10 2006 048 023 B3, DE 100 65 914 A1 and EP 0234623 B1.
- Alloy components such. B. chips, is used.
- cored wires The disadvantage of cored wires is that the filling materials often in Granulatq. Powder form so that the cored wire usually not 100% with the
- Filling material is filled. This leaves a gap volume in the filler wire, which are filled with air or the filling materials are interspersed with air. As the period of time increases, the effectiveness of the filler decreases due to the reaction of the oxygen content of the air with the filler. There may be oxidation reactions between the oxygen present in the air volume and the filler.
- the object of the present invention is to provide a manganese-containing starting material, which is produced by powder metallurgy, to provide that manages without sheathing, and to provide a method for its preparation.
- the manganese-containing starting material produced by powder metallurgy for producing a light metal alloy has a composition which is described by the formula Mnio x -y-zA x ByC z , where A is at least one of the elements cerium (Ce), lanthanum (La) or a Ce misch metal, B is scandium (Sc) and C is zirconium (Zr), and x, y, z are the ranges of compositions of 0 ⁇ x ⁇ 37% by weight, 0 ⁇ y ⁇ 4% by weight and 0 ⁇ z ⁇ 9% by weight.
- the starting material may be formed as a wire or as a plurality of wires twisted together without a sheath or a sheath.
- Preparation of the wires as a starting material for producing a light metal alloy can be done in two ways.
- the metallic constituents of the starting material are transferred individually or in combination by gas atomization in powder form.
- the pulverized components are mixed according to the desired composition of the starting material and in a third step in a
- Pressing cylinder filled and formed by hot isostatic pressing into a bolt In hot isostatic pressing, the press cylinder is inserted into a heatable pressure vessel in which the powder is then compressed at temperatures of up to 2000 ° C, preferably below the solidus temperature of the highest melting temperature constituent, and under pressures of 100 to 200 MPa under inert gas becomes. The gas pressure acts on all sides of the bolt so that the bolt receives isotropic properties.
- the bolt thus obtained is deformed by means of an extruder with a perforated die to form a wire and then the wire is minutecoilt.
- Hole die can have one or more holes, so that several wires can be produced by extrusion at the same time.
- a melt can be generated from the constituents of the starting material, which is then formed by means of a sputtering process to a spray-compacted bolt.
- the spray-compacted bolt also has isotropic properties and is deformed to at least one wire by means of an extrusion die with a perforated die.
- the formed into a wire material can be used for the treatment of melts, in particular by means of wire injection for the production of light metal alloys.
- the alloys may include both magnesium and aluminum alloys.
- the formed as a wire starting material may have a diameter of 1 mm to 25 mm. Since the wire for wire injection with larger diameter are becoming more rigid, they are preferably formed as twisted wires in the form of ropes. This keeps the wires flexible.
- the wire formed as a starting material for wire injection of melts for the production of light metal alloys, it is only important that the starting material has a defined composition.
- a magnesium alloy having the composition 96.75 wt% Mg, 1.9 wt% Mn, 0.6 wt% Ce, 0.3 wt% La, 0.15 wt% Sc and 0.3 wt % Zr.
- the alloying components manganese, cerium, lanthanum, scandium and zirconium are produced individually by gas atomization under protective gas in powder form. Subsequently, the powders are mixed according to a preferred embodiment.
- the powder mixture contains 60% by weight of Mn, 18% by weight of Ce, 9% by weight of La, 4% by weight of Sc and 9% by weight of Zr.
- the powder mixture thus obtained is filled in a press cylinder and formed into a bolt by means of hot isostatic pressing.
- the hot isostatic pressing is preferably carried out under a pressure of 150 MPa and a temperature of about 1000 ° C. This leads to an almost complete compaction of the particles and filling of the pore spaces. Since some of the constituents have melting points below a temperature of 1000 ° C, a combination of solid phase and liquid phase sintering occurs.
- the bolt thus obtained is then deformed by means of an extruder into a wire, which is notedcoilt after exiting the die of the extrusion die.
- the wire preferably has a diameter of 2 mm as the starting material for alloying the magnesium melt.
- the main component (pure metal) is pure magnesium (HP grade), which is free of impurities, used and melted in a metallurgical vessel. The alloying of the molten magnesium takes place by means of
- Wire feeder introduced into the melt.
- Addition amount of the starting material can be precisely controlled via the wire feed device and thus reproducibly introduced into the melt.
- the powder metallurgy production of the starting material has the further advantage that alloy components that can not or only with difficulty melt metallurgy can be processed into a master alloy, can still be made into a raw material in the form of a solid wire, without it being an envelope or a jacket requirement.
