Description
Technical Field
The invention provides a light high-strength high-toughness high-damping titanium alloy and a preparation method thereof, belonging to the technical field of metal materials.
Background
The damping alloy not only can convert mechanical vibration energy into heat energy and dissipate the heat energy, but also has better mechanical properties. The damping alloy is a key material integrating functions and structures in the important engineering fields of key manufacturing, equipment and the like.
The application requirements of the damping alloy for light weight are increasingly urgent, and compared with the traditional Fe-Mn-based and Mn-Cu damping alloy, the titanium alloy has the advantages of light weight, high strength, strong thermal stability and the like, and is paid more attention. The alloy components and the preparation process of the titanium alloy directly influence the damping performance of the titanium alloy, and how to balance the structural characteristics and the functional characteristics of the titanium alloy so as to obtain the titanium alloy with high damping, light weight and good performance is the key of titanium alloy manufacturing application. Because the damping performance of the titanium alloy is generally not high, the damping coefficient of the TC4 titanium alloy which is most widely used at present is 0.0034. Although the TC4 alloy has excellent structural mechanical properties, the damping performance does not meet the vibration reduction and noise reduction requirements of engineering application, and the popularization and the application of the titanium alloy in the vibration reduction and noise reduction damping alloy are severely restricted. Patent CN109097626a proposes a metastable beta titanium alloy with high damping characteristics and ageing stability. The kinetic stabilization of the beta phase is performed by adding beta stabilizing elements Mo, V, zr, etc. Meanwhile, the density of the titanium alloy is maintained within the range of the conventional titanium alloy by optimizing and combining a large number of various cheap elements. Finally, the final titanium alloy is prepared through forging processing and solution treatment. The preparation method of the titanium alloy has complex procedures, complex and diverse alloy elements, various refractory metals and high metallurgical difficulty. In order to promote the development of light weight of vibration reduction noise reduction damping alloy and meet the engineering requirement background of light weight of damping alloy, development of light weight high strength and toughness high damping titanium alloy capable of being applied to mass production is needed.
Disclosure of Invention
The invention aims to overcome the problems that the damping performance of the titanium alloy is poor and cannot be applied to the field of alloy damping, and provides a light high-strength high-damping titanium alloy and a preparation method thereof.
The technical scheme adopted by the invention for achieving the aim of the invention is as follows: a preparation method of a light high-strength high-toughness high-damping titanium alloy comprises the following steps:
S1, proportioning: the simple substance metal block is prepared according to the following mass percent: 77-82% of titanium, 2-4% of aluminum, 13-15% of vanadium and 2.5-6% of iron;
S2, vacuum melting: placing the prepared simple substance metal block into a high-vacuum non-consumable arc melting furnace for vacuum melting, wherein the number of times of vacuum melting is 5-6, each time of melting is 3-5 min, and the arc current is controlled to be 350-500A in the melting process; cooling the melted alloy in a melting furnace along with the furnace to obtain a titanium alloy cast ingot;
S3, thermo-mechanical treatment: carrying out vacuum homogenization treatment on the titanium alloy ingot at 800-900 ℃ for 120-150 min, and then carrying out water quenching; cold rolling the alloy after water quenching, wherein the cold rolling reduction is 30-50%; and finally, carrying out vacuum stress relief annealing on the cold-rolled alloy to obtain the light high-strength high-toughness high-damping titanium alloy.
Further, the volume of the simple substance metal block in the step S1 is 113.1mm 3～452.39mm3.
Further, the simple substance metal blocks are prepared according to the following mass percent in the process of batching in the step S1: 78-80% of titanium, 2-3% of aluminum, 13.5-15% of vanadium and 3.5-5% of iron.
Further, the total weight of the simple substance metal blocks used for vacuum smelting in each high-vacuum non-consumable arc smelting furnace is 200-250 g.
Further, in the vacuum smelting in the step S2, the vacuum degree in the vacuum smelting furnace is ensured to be 6.0x10 < -3 > to 7.0x10 < -3 > Pa.
Further, in the step S2, the prepared simple substance metal blocks are placed in a high-vacuum non-consumable arc melting furnace for vacuum melting, wherein the aluminum metal blocks are placed at the bottom, and the vanadium metal blocks are placed at the top.
Further, before cold rolling in the step S3, the titanium alloy cast ingot is subjected to vacuum homogenization treatment for 130-140 min at 830-870 ℃, and then water quenching is carried out.
Further, the cold rolling reduction of the step S3 is 37.5 to 44.5 percent.
Compared with the prior art, the invention has the beneficial effects that:
The existing titanium alloy is prepared by complex surface treatment or adding noble metal elements such as zirconium, niobium, hafnium and the like, and has high damping performance and high strength and toughness, and has complex process and higher cost. The mass of the titanium alloy is increased while a large amount of noble metal elements such as zirconium, niobium and hafnium are introduced, so that the aim of light weight cannot be achieved. According to the invention, a certain amount of non-noble alloying element and titanium alloy beta-phase stabilizing element Fe are added into the titanium alloy, so that the damping performance and mechanical property of the titanium alloy are optimally balanced while the beta-phase is stabilized, and the light high-strength high-toughness high-damping titanium alloy is obtained.
When the content of the added Fe element is small, the beta phase of the titanium alloy is not stable enough, and the solid solution strengthening effect generated by the Fe element is not obvious. When the content of the added Fe element is excessive, segregation phenomenon is easy to occur in the smelting process, the strength of the titanium alloy is improved, and the damping performance of the titanium alloy is adversely affected. A large number of experiments show that the damping performance and the mechanical performance of the titanium alloy can be optimally balanced while the beta phase of the titanium alloy is stable only when 2.5-6wt% of Fe element is added.
