Description
Technical field
The present invention relates to a kind of alloy, more particularly to a kind of intermediate alloy for being used to prepare titanium alloy, and it is related to preparation side
Method and purposes.
Background technology
Titanium alloy is obtained with its excellent specific strength, corrosion resisting property etc. in the field such as Aero-Space and chemical industry widely should
With to adapt to the requirement of a variety of Service Environments, the alloying element composition of titanium alloy also tends to development in pluralism.It is alloy properties to ensure
The stability of energy, adds suitable intermediate alloy and is particularly important, otherwise easily cause high density to be mingled with, low-density is mingled with, β
The defects of spot.The intermediate alloy of diversification improves the physical property of intermediate alloy, can effectively improve the alloying component uniformity, and
And overcome segregation, scaling loss etc. is reduced, therefore, for the preparation of titanium alloy, especially containing easy segregation element or infusibility
The titanium alloy of element, the intermediate alloy of diversification is a kind of selection well.
In the melting of titanium alloy, Nb and Mo belong to high-melting-point element, and Mo elements belong to easy segregation element, melting
It is improper to be controlled in journey, easily causes element segregation, forms high density and is mingled with, or the defects of β spots, has a strong impact on the mechanics of alloy
Performance, adding Mo and Nb etc. by the intermediate alloy of diversification then can effectively avoid such risk.
The content of the invention
Therefore, the technical problem to be solved in the present invention is to provide it is a kind of for titanium alloy prepare four element intermediate alloys,
The alloy is used for preparing the titanium alloy containing a variety of alloying elements, while reducing titanium alloy metallurgy risk, reduces production system
Cause this.
The technical scheme is that a kind of four element intermediate alloys prepared for titanium alloy, the quality of chemical element
Percentage, it is as follows：
Mo：9-15%
Nb：30-40%
Zr：20-30%
Surplus is Al and other inevitable impurity；
The fusing point of the four elements intermediate alloy is between Al fusing point and Mo fusing point.
According to a kind of four element intermediate alloys prepared for titanium alloy of the present invention, it is preferred that the alloy is
It is granular, granularity 0.3-10mm.
According to a kind of four element intermediate alloys prepared for titanium alloy of the present invention, it is preferred that in four element
Between the fusing point of alloy be 1850-1950 DEG C of
Present invention also offers a kind of preparation method of the four element intermediate alloys prepared for titanium alloy, including metal fever
Reducing process, using aluminium as reducing agent, molybdenum trioxide, niobium pentaoxide, zirconium dioxide are oxidant, and calcirm-fluoride is slag former, are used
Metallothermic processes prepares the quaternary alloy；In the metallothermic processes smelting process, aluminium powder, molybdenum trioxide, five oxidations two
Niobium, the weight ratio of zirconium dioxide are (0.30~0.50)：(0.09~0.12)：(0.25~0.40)：(0.15~0.25), fluorination
Calcium addition is the 5%-20% of gross weight.
In addition, four element intermediate alloys prepared by above-mentioned titanium alloy are additionally provided in titanium alloy is prepared as raw material
Purposes.
The beneficial effects of the invention are as follows：
It can be seen from the phase diagram knowledge of multicomponent alloy, the fusing point of the quaternary alloy should Al fusing point and Mo fusing point it
Between.Verify after tested, the fusing point of the quaternary alloy is about 1900 DEG C, and the fusing point of pure titanium is 1668 DEG C, the quaternary alloy
Fusing point is closer to pure titanium fusing point, greatly reduce different melting points between intermediate alloy and pure titanium it is excessive may caused by it is highly dense
Degree is mingled with, the probability formed the defects of segregation.By repetition test, select suitable slag former, determine aluminium powder, molybdenum trioxide,
The rational proportion of niobium pentaoxide, zirconium dioxide, finally give the quaternary intermediate alloy of proper properties so that among four element
Alloy improves the stability of fusion process in titanium alloy preparation process, ensure that the uniformity of ingot chemistry, ensures
The tissue of alloy and the stability of performance.
