Definitions
- the invention relates to a process for the production of ⁇ -TiAl base alloys by means of vacuum arc melting (VA) which solidify completely or at least partially primarily via the ⁇ -phase.
- VA vacuum arc melting
- target alloys will hereinafter be referred to as ⁇ - ⁇ -TiAl base alloy.
- the technical field of the present invention is the melt metallurgical production of ⁇ - ⁇ -TiAl alloys by means of vacuum arc melting (VAR).
- VAR vacuum arc melting
- step (ii) at least one remelting of the electrodes obtained in step (i) by a conventional melt metallurgical process
- Diameter. DE 195 81 384 TI describes intermetallic TiAl compounds and processes for their preparation, wherein the alloy by heat treatment of an alloy having a Ti concentration of 42 to 48 atom%, an Al concentration of 44 to 47 atomic%, a Nb concentration of 6 to 10 atom% and a Cr concentration of 1 to 3 atom% at a temperature in the range of 1300 to 1400 ° C is prepared.
- DE 196 31 583 A1 discloses a method for producing a TiAl-Nb product from an alloy, in which first an alloy electrode is produced from the alloy components. The formation of the alloy electrode is carried out by pressing and / or sintering the alloy components to the electrode. The latter is melted off by an induction coil.
- JP 02277736 A discloses a heat-resistant TiAl-based alloy in which specific amounts of V and Cr are introduced into an intermetallic Ti-Al compound to improve heat resistance and ductility.
- DE 1 179 006 A discloses ternary or higher titanium-aluminum alloys with such elements which stabilize the ⁇ - and ⁇ -phase of the titanium.
- the usual process for remelting is vacuum-arc melting with self-consuming electrode, since the plasma melting plants are generally not designed for the supply of compact ingots as starting material.
- biphasic in the form of lamellar colonies of the a2-Ti 3 Al phase and the ⁇ -TiAl phase constructed ⁇ -TiAl base alloys remelting takes place in the vacuum arc furnace (VAR furnace) easily and leads to the desired result (see V. Guether: "Status and Prospects of ⁇ -TiAl Intote Production", International Symp. on Gamma Titanium Aluminides 2003, ed. H. Clemens, Y.-W. Kim and AH Rosenberger, San Diego, TMS 2004).
- a new generation of ⁇ -TiAl high performance materials has a structural design different from conventional TiAl alloys.
- ß-stabilizing elements such as Cr, Cu, Hf, Mn, Mo, Nb, V , Ta and Zr
- a primary solidification path is established over the ⁇ -Ti phase. This results in very fine microstructures, in addition to lamellar ⁇ 2 / ⁇ - Colonies also include globular ⁇ grains and globular ⁇ grains, sometimes including globular 012 grains.
- the disadvantage is that cracking occurs again during the remelting of electrodes from this material in the VAR furnace, the result of which is frequently the flaking off of constituents of the self-consumable alloy electrode from the primary melting zone. These chipped parts fall into the molten bath and are no longer completely remelted therein. This causes structural defects in the ingot, making the ingot material unusable. Remelting in the VAR furnace is no longer technically reproducible under these conditions.
- the cause of the disturbing chipping behavior is considered to be massive phase transformations in the temperature range between the eutectoid temperature and the phase boundary temperature to the ⁇ -phase region.
- the curve represents the During VAR melting, based on the length of the self-consumable electrode, a temperature field extends from the melting temperature (about 1570 ° C.) at the bottom of the electrode to near room temperature at the electrode suspension between 1000 and 1200 ° C.
- the relatively poor ductility of the intermetallic material then leads in this zone to the formation of the S Tear discharges in the form of cracks, which in turn lead to the described chipping of unmelted pieces of the electrode.
- the present invention seeks to provide a method for producing a solidifying over the ⁇ -phase ⁇ -TiAl base alloy - hereinafter referred to as ⁇ - ⁇ -TiAl base alloy - specify that Avoiding the cracking problem leads to a reliable production of such a target alloy.
- the successive remelting steps during the vacuum arc melting are thus subdivided into the melting of a primary alloy in the first remelting steps, wherein a base melt electrode is produced from a conventional ⁇ -TiAl primary alloy, and the melting of the target alloy in the form of the desired ⁇ - ⁇ -TiAl base alloy in the last remelting step.
- the primary alloy has a deficit of titanium and / or a deficiency of ß-stabilizing elements such as Nb, Mo, Cr, Mn, V, and Ta.
- the alloy is a defined amount of titanium and / or ß deprived of stabilizing elements, so that an aluminum content of the primary alloy preferably between 45 at .-% (particularly preferably 45.5 at .-%) and 50 at .-% sets.
- the contents of aluminum and ß-stabilizing elements are chosen so that the solidification path of the primary alloy is at least partially via the peritectic conversion. It is thus set a structure analogous to conventional TiAl alloys, which can be processed easily in VA oven.
- the target alloy is readjusted by the addition of the materials originally removed from the press electrode.
- these materials are welded as cladding to form a composite electrode firmly on the outer surface of the Abschmelzelektrode to safely exclude a solid state drop into the molten bath. It is also possible to accomplish this by a sheath insert of the deficient alloy content on the inside of the Umschmelzkokille the VAR furnace.
