Definitions
- the invention relates to the field of metallurgy, in particular to the creation of modern titanium alloys used for the manufacture of high-strength and high-tech products, including large ones, i.e. alloys with a high degree of versatility.
- Titanium alloys are widely used as aerospace materials, for example, for airplanes and rockets, because alloys have strong mechanical properties and are relatively lightweight.
- TibAWV (Kalachev B.A., Polkin I.S. and Talalaev V.D. Titanium alloys from different countries. Handbook. M .: VILS, 2000, p. 58-59) - [1].
- the alloy was developed in the USA in the 50s. Alloy of medium strength from 850 to 1000 MPa and high technology. It is well processed by pressure: forging, stamping, pressing. Found wide application in aviation and aerospace engineering, shipbuilding, automotive industry, etc., as well as for the manufacture of fastener parts for various purposes.
- the alloy is well processed by all types of welding, including diffusion.
- the disadvantage of Ti6A14V alloy is its lack of versatility.
- the known pseudo- ⁇ -titanium alloy Grade 9 (Ti-ZA1-2.5V), as an alloy having a high ability to cold deformation (see [1], with 44.45). It has intermediate strength of the alloy Ti-6A1-4V and titanium (600-800 MPa). It is used in the cured state and after annealing to relieve stresses; It has high corrosion resistance in many environments, including seawater. Used for the manufacture of pipes for the hydraulic and fuel systems of aircraft, rockets, submarines.
- a disadvantage of the known alloy is also its low versatility, due to the fact that in the manufacture of large-sized structural products it is mandatory to relieve internal stresses. To this end, the products are annealed, while the strength characteristics of the Grade 9 alloy are reduced to 400-500 MPa.
- the closest analogue to the claimed invention is ⁇ + ⁇ -titanium fame, comprising 3.0-5.0 Al; 2.1-3.7 V; 0.85-3.15 Mo; 0.85-3.15 Fe; 0.06-0.2 O 2 and inevitable impurities (Japanese application J ⁇ 3007214 B2, publ. 07.02.2000) - prototype.
- the problem to which this invention is directed is to create a universal titanium alloy with the lowest cost for its manufacture and the ability to produce from it a wide range of products from titanium alloys, such as bulky forgings and stampings, as well as sheet metal and foil with the required strength - ny and plastic characteristics and structure.
- the technical result achieved by the implementation of the claimed invention is to regulate the optimal combination of ⁇ - and ⁇ -stabilizing alloying components in the finished semi-finished product.
- the technical result is achieved by the fact that in a titanium-based alloy consisting of aluminum, vanadium, molybdenum, iron and oxygen, according to the invention, the components are taken in the following ratio, May. %:
- Titanium rest The combination of high strength and technological plasticity of the proposed alloy is achieved as a result of a targeted selection and experimental assessment of alloying ranges.
- the content of ⁇ -stabilizing elements (aluminum, oxygen) and ⁇ -stabilizing elements (vanadium, molybdenum and iron) are selected necessary and sufficient to achieve the goal.
- Aluminum is an ⁇ -phase stabilizer for ⁇ + ⁇ -titanium alloys, which provides an increase in mechanical strength.
- the aluminum content of the inventive alloy is less than 3.5%, the required strength cannot be achieved. If the aluminum content exceeds 5%, the resistance to hot deformation increases and the deformability at lower temperatures deteriorates, which leads to a decrease in productivity.
- Vanadium is added to titanium as a ⁇ -phase stabilizer for ⁇ + ⁇ -titanium alloys, which provides an increase in mechanical strength without forming brittle intermetallic compounds with titanium.
- the presence of vanadium in the alloy as the ⁇ phase stabilizes makes it difficult to form an ⁇ 2 superstructure in the ⁇ phase and helps to increase not only strength properties, but also ductility.
- the content of vanadium is less than 2%, sufficient strength, which must be obtained on the basis of the invention, cannot be achieved. If the vanadium content exceeds 4.0%, superplastic elongation is reduced due to an excessive decrease in the polymorphic transformation temperature.
- the content of vanadium in the range of 2.0-4.0% in this alloy has the advantage of the fact that the waste of the Ti6A14V alloy, which is widely used in our enterprise, can be used to obtain it.
- Molybdenum is added to titanium as a ⁇ -phase stabilizer for ⁇ + ⁇ -titanium alloys.
- the introduction of molybdenum in the pre- 0.1–0.8% ensures its complete solubility in the ⁇ phase, which makes it possible to obtain the necessary strength characteristics without reducing the plastic properties. If the molybdenum content exceeds 0.8%, the specific gravity of the alloy increases due to the fact that molybdenum is a heavy metal, and the plastic properties of the alloy are reduced. A molybdenum content of less than 0.1% does not provide the full properties of the alloy.
- the introduction of iron into the alloy up to 0.4% increases the volume fraction of the ⁇ phase, decreasing the resistance to deformation during hot working of the alloy, which helps to avoid the formation of defects such as cracks.
- An iron content of more than 0.4% leads to segregation processes with the formation of “beta-fluxes” during melting and crystallization of the alloy, which leads to heterogeneous mechanical properties, in particular ductility.
- Oxygen provides an increase in mechanical strength during the formation of a solid solution, mainly in the ⁇ phase.
- An oxygen content of more than 0.25% can lead to a decrease in the plastic properties of the alloy.
- the proposed alloy in comparison with the known ones, has high versatility, is economically profitable, has a lower cost, due to the fact that waste from widely known alloys, for example, Ti6A14V alloy, is used for its production.
- This alloy has the necessary and sufficient level of mechanical properties and can be used by deformation both in the ⁇ + ⁇ -region and in the ⁇ -region for the manufacture of a wide range of products, including large-size stampings and forgings, as well as thin sheets and foil.
