Description
Technical field
The present invention relates to field of metallurgy, and in particular to a kind of high intensity tungsten molybdenum alloy.
Background technology
The alloy that tungsten-molybdenum alloy is mainly made of tungsten and molybdenum, its corrosiveness with excellent tolerance of liquid zinc, to
Manufacture the blender in zinc metallurgy industry, pipeline and container inside lining and miscellaneous part.And tungsten-molybdenum alloy due to elevated temperature strength it is good, performance
It is close with tungsten and proportion is smaller than tungsten, so can be used as the high-temperature component under corresponding hot conditions in rocket, guided missile, electron tube
Filament, part and other high-temperature materials, it is widely used.The present invention improves on the basis of having studied by multiple component
A kind of and experiment, there is provided scientific formula of high intensity tungsten molybdenum alloy so that the tungsten-molybdenum alloy being prepared has corrosion resistance,
The characteristics such as good elevated temperature strength, hardness.
The content of the invention
In view of object above, the invention discloses a kind of high intensity tungsten molybdenum alloy.
To achieve these goals, the technical solution adopted by the present invention is：A kind of high intensity tungsten molybdenum alloy, includes following matter
Measure the component of percentage：Rare earth REINFORCED Al2O3Doping molybdenum based composite powder 35-45%, tungsten 45-55%, metal binding agent 4-6%,
Potassium 1-2%, nano boron carbide 1-3%, zirconium 2-4%.
The rare earth REINFORCED Al2O3Doping molybdenum based composite powder is La2O3/Al2O3/ Mo mixed powders, average grain diameter is in 1-
2um.Wherein, La2O3/Al2O3The preparation method bibliography of/Mo mixed powders《Rare earth REINFORCED Al2O3Doping molybdenum based composite powder
Preparation》Material heat treatment technology Material＆Heat Treatment [J] .2012.41 (06):70-73.
The metal binding agent is made of the raw material of following quality proportionings：
Nickel 2-4%, silicon Si 1.5-3%, cobalt Co 85-90%, rhenium Re 4-8%, titanium Ti 1-3%.
The particle diameter of the nano boron carbide is 30-50um.
Rare earth REINFORCED Al2O3Doping molybdenum based composite powder introduces rare earth oxide La on the basis of original molybdenum base matter2O3With
Al2O3Crystal, can not only improve the recrystallization temperature and high-temperature creep resistance of molybdenum, and can substantially reduce crisp turn of the modeling of molybdenum
Temperature, increases its extensibility, improves brittleness at room temperature and high temperature sag resistance ability of molybdenum etc.；Add Al2O3Also add while crystal
Corrosion resistance, heat resistance, intensity and hardness of the composite granule etc. are added, have made its function simply folded better than one of independent powder
Add.
Metal Elements K, zirconium, nano material boron carbide etc. can not only close in crystal grain thinning, increase in alloy formation process
Golden intensity；It can also effectively suppress the generation and extension of crackle, improve alloy HAVING A GRACEFUL FIGURE.
Beneficial effects of the present invention：The tungsten-molybdenum alloy scientific formulation of the present invention is reasonable, and rare earth is added in tungsten-molybdenum alloy and is increased
Strong Al2O3Doping molybdenum based composite powder substitutes simple molybdenum, then adds Metal Elements K, zirconium, nano boron carbide etc., not only acts as
The effect of toughness reinforcing intensity also has the advantage of refinement internal grain, while improves the brittleness at room temperature and high temperature sag resistance ability of molybdenum
Deng so that the tungsten-molybdenum alloy being prepared has the characteristics such as corrosion resistance, good elevated temperature strength, hardness；Its uniaxial tension is strong
Degree is up to 800-950MPa, and yield stress is up to 900-1000MPa, and hardness is up to 240-260HBS.
