Description
Technical Field
The invention relates to the field of metal materials, in particular to a non-magnetic width Wen Yuheng elastic titanium alloy and a preparation method thereof.
Background
As early as the early 19 th century, it was found that temperature changes affect the accuracy of the travel time of a timepiece, and it was gradually recognised that this phenomenon was related to the change in modulus of elasticity of the balance spring in a timepiece with temperature. In later researches, it is found that for general metals or phase-change-free alloys, the elastic modulus of the alloys tends to decrease with the increase of temperature due to the gradual decrease of the interatomic bonding force, and the change relation of the elastic modulus with temperature is extremely unfavorable for the accuracy of the instruments and meters used under different temperature environments. Therefore, in order to ensure the accuracy and reliability of the instruments and meters used in different temperature environments, it is highly desirable to develop a material with a small elastic modulus that does not change or changes with temperature in a certain temperature range, and the material has a small elastic modulus temperature coefficient and may also be called as constant elastic Ai Linwa (Elinvar) alloy.
In 1896, it was found that when the atomic percentage of Ni in the fe—ni binary alloy is 42%, the elastic modulus temperature coefficient can be close to zero, but the constant elastic temperature range is very narrow and the mechanical properties are poor, so that the use is not widely achieved. Thereafter, carbide-strengthened and age-strengthened Fe-Ni-based constant elastic alloys have been developed for practical use, forming a number of brands, such as: ni-Span C, ni-Span D and 3J53, 3J58 and other constant elastic alloys in China. Because of factors such as poor performance consistency, low mechanical quality factor and the like of the Fe-Ni alloy, a great deal of work is carried out at home and abroad, and various constant elasticity alloys are researched to make up for the defects of the Fe-Ni alloy. One of the types is ferromagnetic constant elastic alloy, which is mainly Fe-Ni and Fe-Co alloy, and Mo, cu, zr, ge and rare earth elements can be added in proper amount to further reduce the temperature coefficient of elastic modulus, so that the form and the quantity of precipitated phases are changed, and a novel constant elastic alloy with more excellent performance is developed. The ferromagnetic constant elastic alloy with wider application is Co-Fe alloy, the elastic modulus temperature coefficient is stable, and typical alloy is Elcolly alloy, etc. In the instrument industry, most of the elastic elements are not interfered by external magnetic fields or the working magnetic fields of instruments, so that the ferromagnetic constant elastic alloy cannot meet the requirement of use under the magnetic fields, and therefore, a novel nonmagnetic constant elastic alloy needs to be developed and researched.
The nonmagnetic constant elastic alloy is mainly divided into two types, wherein the first type is antiferromagnetic constant elastic alloy, and the antiferromagnetic constant elastic alloy comprises Cr-based alloy systems, fe-Mn-based alloy systems, mn-based alloy systems and the like; another class is paramagnetic and chemoelastic alloys, such as: nb-based, ti-based, pd-Au-based alloys, and the like. The Fe-Mn alloy and Mn alloy are characterized by low cost, but have narrow constant elastic temperature range and poor corrosion resistance, so that the use environment with high precision requirement and large temperature change cannot be satisfied. The paramagnetic Nb-based constant elasticity alloy has excellent performance and wider constant elasticity temperature area, but is difficult to process, and Pd-Au alloy has high cost and cannot be widely applied. Compared with the Ti-based alloy, the Ti-based alloy has the advantages of no magnetism, high corrosion resistance, high elasticity limit, high fatigue limit, high tensile strength, high yield strength, good plasticity and the like, and the constant elasticity temperature zone is relatively wide, so that the Ti-based alloy meets the applicable conditions in the aspects of aerospace navigation instruments, meters and the like, and has extremely high application potential. However, at present, few domestic patent reports on Ti-based constant elastic alloy with excellent comprehensive performance are provided, and related constant elastic materials are not widely applied, so that the wide Wen Yuheng elastic titanium alloy has higher research and application values.
Disclosure of Invention
The invention aims to provide a non-magnetic width Wen Yuheng elastic titanium alloy with excellent comprehensive mechanical properties and a preparation method thereof, which meet the special requirements of elastic elements (such as a pressure sensor, a strain gauge calibrating beam, a torsion bar gyroscope and the like) applied in a wide temperature range on material properties for realizing high precision, high sensitivity and high disturbance rejection capability.
In order to achieve the above purpose, the technical scheme of the invention is as follows:
the elastic titanium alloy without magnetic width Wen Yuheng contains at least one or more than two beta stabilizing elements in percentage by weight: nb, ta, mo, V, the content of which is 10-40%; may contain one or two neutral elements as required: zr and Sn, the total content is 0-20%; one or more than two alpha stabilizing elements may be contained as needed: al and O with the content of 0-5%; the balance being Ti.
The non-magnetic width Wen Yuheng elastic titanium alloy has constant elastic modulus within a wide temperature range of-150-350 ℃.
The elastic modulus temperature coefficient of the nonmagnetic wide Wen Yuheng elastic titanium alloy is less than 20 multiplied by 10 within the wide temperature range of-150 ℃ to 350 DEG C -6 /℃。
The elastic modulus temperature coefficient of the non-magnetic width Wen Yuheng elastic titanium alloy is less than 0.5X10 within the temperature range of minus 50 ℃ to 50 DEG C -6 /℃。
The elastic modulus of the nonmagnetic wide Wen Yuheng elastic titanium alloy is 60-90 GPa, and the yield strength is more than 600MPa.
According to the preparation method of the non-magnetic width Wen Yuheng elastic titanium alloy, the volume fraction and the lattice parameter of an alpha' phase of an orthogonal structure of the alloy are regulated and controlled through heat treatment, the heat treatment temperature is 250-550 ℃, and the heat treatment time is 0.5-48 hours.
The design idea of the invention is as follows:
conventional ferromagnetic constant elastic alloys rely on magnetic correlation mechanisms such as: the modulus hardening caused by magnetic shrinkage and the modulus softening caused by atomic thermal shock are offset to cause macroscopic constant elasticity performance of the alloy. Other non-magnetic constant elastic alloys can regulate and control the elastic performance through antiferromagnetic-paramagnetic transformation, phase change, cold working, texture introduction and other modes, which are relatively complex and are interfered by an external magnetic field. Whereas for beta titanium alloys, heat treatment can introduce a large number of nanoscale metastable transition phases that can significantly adjust the elastic properties of the alloy. After being regulated by a proper heat treatment system, the alloy can show constant elasticity in a certain temperature range.
The wide Wen Yuheng elastic titanium alloy and the preparation method thereof provided by the invention have the advantages and beneficial effects that:
1. the invention providesThe wide Wen Yuheng elastic titanium alloy has the advantages of high strength, wide use temperature range, good plasticity and constant elasticity, and is particularly as follows: the alloy has yield strength greater than 600MPa, constant modulus temperature range of-150-350 deg.c, elongation rate 8-20% and elastic modulus temperature coefficient less than 20 x 10 -6 And the product has excellent comprehensive performance at the temperature of every DEG C. The material is nonmagnetic, so that the function of the material is not interfered by an external magnetic field, and the working magnetic field in the actual working environment is not influenced by the existence of the material, thereby remarkably improving the magnetic field stability and the anti-interference characteristic.
2. Compared with the traditional constant modulus material, the preparation method of the wide Wen Yuheng modulus titanium alloy provided by the invention has the advantages that the alloy performance is independent of the adjustment of original components, the method can obtain the expected modulus temperature change relation only by adjusting the aging temperature and the aging time without changing the original components of the material from the source, so that the production and the use are greatly facilitated, the product consistency is good, the unprecedented good technical effect is achieved, and the application of the method has huge economy.
3. The preparation method of the wide Wen Yuheng modulus titanium alloy is suitable for a series of beta titanium alloys capable of aging out the precipitated phases of the orthogonal structure, so that the preparation method is free from the original components of the titanium alloy, and the heat treatment process can be changed according to the requirements, thereby realizing that the beta titanium alloy with different components obtains the constant modulus characteristic.
