Description
Technical field
The present invention relates to Material Field, more particularly to a kind of high temperature resistant Flouride-resistani acid phesphatase nuclear field alloy and preparation method and use
On the way.
Background technology
With the continuous improvement of human living standards, the demand to the energy particularly electric energy increases year by year.Current electric energy
Mainly obtained by approach such as thermal power generation, hydroelectric generation, wind-power electricity generation, solar power generation, nuclear energy power generations.Because of ecological requirements,
Thermal power generation proportion is less and less, and hydroelectric generation, wind-power electricity generation and solar power generation seasonal variety are substantially, generated energy
Unstable, application region is limited.Comparatively, nuclear energy power generation occupies little space, generating efficiency is high, generated energy is stable, therefore
To fast development.
Nuclear power station generating nucleus temperature is high, there is strong irradiation, and the equipment performance requirement to being used in nuclear field is strict.
Such as, the material containing disk for charge that current nuclear field is used, is made of molybdenum materials matter, and its fusing point is relatively low, vapour pressure is larger, is made
Material containing disk intensity is relatively low, yielding at high temperature, laminated multi-layer and loaded material, by easily being sticked together after high temperature sintering, leads
It is abnormal difficult that cause picks and places material in radioactive element isolation environment.
Refractory metal such as tungsten (W), molybdenum (Mo), tantalum (Ta), niobium (Nb), rhenium (Re) have high-melting-point, high rigidity, high intensity,
The characteristics such as high density, recrystallization temperature high, low vapour pressure, low electron work functon, are resistant to intense radiation and irradiate and shield
Irradiation is covered, is very suitable for the application in high temperature nuclear field field, meanwhile, high-melting-point and low-steam pressure are carried to prepare high-purity agglomerated material
Supply to ensure.
Therefore, high temperature resistant, radiation-resistant property of the alloy in nuclear field hot environment how are increased substantially, preparation is processed
Sintering container intensity it is high, hardness is big, resistance to blocking is strong, is those skilled in the art's problem demanding prompt solution.
The content of the invention
An object of the present invention is to provide a kind of high temperature resistant Flouride-resistani acid phesphatase nuclear field alloy and preparation method and purposes, this
The intensity of alloy, hardness and fusing point improve notable, with good high-temperature stability and high-temperature creep resistance, the nuclear field of preparation
Material containing disk has the advantages that deflection is small, multiple-layer overlapped is difficult adhesion under nuclear field hot environment, and sintering environment can be effectively ensured
Purity.
The second object of the present invention is to provide a kind of nuclear field material containing disk, this nuclear field material containing disk high temperature resistant, anti-radiation performance
By force, saturated vapor is forced down, and the purity of sintering environment can be effectively ensured.
Realizing the technical scheme of one of the object of the invention is：A kind of high temperature resistant Flouride-resistani acid phesphatase alloy, the weight percent of each component
