Description
Technical field
The invention relates to a kind of beta-titanium alloy, particularly a kind of more cheap than existing beta-titanium alloy, be easy to beta-titanium alloy and method of manufacture thereof that suitability for industrialized production and mechanical property can keep peer-level basically.
Background technology
In the titanium alloy system, beta-titanium alloy has the highest specific tenacity (strength/density) and good cold-forming property, is applied as purpose with military project the earliest.And present industrial beta-titanium alloy more and more widely is applied to civil area, for example titanium spectacle frame, miniature mobile TV, navigating instrument, mobile phone, golf club, fishing gear and the body implanting material of recent years etc.Yet infusibility high-density elements such as a large amount of Mo, Nb, Ta, V in beta titanium alloy, have been added in order to stablize β; Cause beta-titanium alloy density acceptable material big, that produce no metal inclusion difficult, cause the beta-titanium alloy cost high owing to added expensive precious metal.Therefore, limited even beta-titanium alloy is also used at military industry field, and civil area has just been used still less.In order to make the beta-titanium alloy broader applications in the beta-titanium alloy that civil area presses for developing low-cost, is prone to industrialization, performance does not reduce.
Table 1 has been listed from beta-titanium alloy and has been invented the composition and the characteristic of all kinds beta-titanium alloy up till now.No.1～13 alloys are traditional beta-titanium alloys, the commercialization that they have, and what have is eliminated, also little even commercial alloy is used.From table, can find out; This type alloy has mostly added infusibility, high-density, the Mo of high price, Nb, Ta metal; And industrial production titanium alloy method is the vacuum consumable arc-melting method, in case above-mentioned metal inclusion appears, even remelting can not be eliminated for ten times fully; Therefore their melting is a technical barrier, and the resultant metal of these alloys is mingled with and is often to produce.Other relative merits of each alloy have not just been commented one by one; But what deserves to be mentioned is that wherein the No.9 alloy is the low-cost beta-titanium alloy of U.S.'s recent development, because it has added 4.5% Fe (iron); Make and to adopt the Mo-Fe master alloy, thereby reduced cost of alloy.But the problem that this alloy exists is that Mo is mingled with also and possibly produces, and the more important thing is that the possibility that the β spot appears in alloy is very big, is to allow to occur the β spot anything but in aerospace applications owing to contain 4.5% Fe.The β spot of rich Fe occurs like the Ti-10V-2Fe-3Al alloy, make the producer have to spend a large amount of time to solve this problem in process of production.
No.14 in the table～16 alloys are the beta-titanium alloys that contain 12% above V, and their advantage is not contain the infusibility high desnity metal, has avoided the generation of metal inclusion, and has reduced alloy density.But because the adding of lot of V descends the oxidation-resistance of alloy, be easy to receive staining of oxygen, cause oxide debris loose; Metal loss is big in hot-work and heat treatment process; The surface quality and the performance of finished product are influenced, and wherein the No.14 alloy is particularly serious, although it has good cold-workability and low alloy density; But its cost is very high, because it adopts pure metal V or high V-Al to add.
No.17 in the table～27 alloys are titanium alloys that are used for body implanting material of recent development; Owing to can not add harmful elements such as V, Al, need have simultaneously and the near Young's modulus of elasticity of people's bone photo, and add metals such as a large amount of Nb, Ta, Hf, Zr; Wherein Nb, Ta, Hf are infusibility, high-density, high price metal; Obviously, first problem is with present industrial production means, is difficult to make their alloyings; Many places solve the breakthrough that their alloying problems await new installation, new technology and novel process in laboratory stage at present.In addition, because Nb, the Ta low mutually stable element that is β, the add-on of table interalloy is not enough to stablize the β tissue, so their solution treatment must adopt frozen water to cool off, and makes thermal treatment process complicated.
In sum, existing beta-titanium alloy exists different shortcomings separately, people wait in expectation excellent property, with low cost, the birth of producing easy beta-titanium alloy.
