Description
Technical field
The present invention relates to the preparation methods of a kind of surface Multi-scale model tungsten material and its material, belong at metal surface
Manage technical field.
Background technique
Service Environment of the fusion reactor towards plasma source components is extremely harsh, it is desirable that material therein can be for a long time
Damage effect caused by high heat load and strong irradiation is resisted, to guarantee the long-term stable operation of fusion reactor.Tungsten is that fusing point is highest
Metal material, and there is high heat conductance, low sputtering raste, it is considered to be it is most potential to can be applied to towards plasma source components
One of material.But the maximum deficiency of tungsten is that have apparent brittleness at room temperature (even rolling state business level tungsten, ductile-brittle transiton temperature
Spend DBTT between 200 DEG C -300 DEG C), radiation embrittlement, thermic load cracking the defects of, significantly limit it as the first wall material
The practical application of material.
In order to improve tungsten above shortcomings, scholars have carried out with tungsten alloy, tungsten/tungsten alloy plastic deformation processing
Tungsten toughness is improved with the approach based on tungsten Surface Nanocrystalline.The principle of these methods is all to induce the crystal grain refinement of tungsten strong
Change.Alloying is generally used in combination with plastic deformation, main by adding second phase nano particle such as oxide carbide etc. more
It dissipates tungsten basal body and prepares fine grain tungsten alloy, and combine subsequent rolling process, achieve the effect that alloy densification, refinement and strengthen.Liu
Auspicious, Xie Zhuoming etc. disclosed in patent CN104388789B " a kind of nanostructure tungsten-carbonization zircaloy and preparation method thereof "
And Xie Zhuoming etc. is in paper " Extraordinary high ductility/strength of the interface
Designed bulk W-ZrC alloy plate at relatively low temperature ", " Scientific
Reports " addition nano-zirconium carbide is reported in 5 (2015) 16014 refines tungsten basal body crystal grain adequately, it obtains a large amount of
Crystal boundary/phase boundary, to make alloy that there is more excellent obdurability and thermal-shock resistance.But shortcoming is to sacrifice the heat of pure tungsten
Conductance, the phase boundary in W-ZrC alloy also enhance the scattering process to electronics while increasing mechanical property, thermal conductivity is compared
Pure tungsten is decreased obviously.Liu Rui etc. is improved mentioned component, and a kind of " potassium carbonization is disclosed in patent CN108149103A
Zirconium codope tungsten alloy and preparation method thereof " further improves the power of tungsten by the collective effect of nanometer potassium bubble and zirconium carbide
Performance is learned, thermal conductivity is not characterized.But it can speculate that presence will make alloy thermal conductivity into one to potassium bubble jointly with ceramic nanoparticles
Step decline.
High thermal conductivity is just conducive to remove the heat being deposited on the first wall in time, can be while improving mechanical property
Tungsten is not lost to have great importance from the thermal conductivity of height yet.Under most of Service Environments, construction instability starts from surface more,
For this purpose, the research of pure tungsten surface self-nanocrystallinzation receives the concern of researchers, because it has the advantage that 1) nano surface tungsten is brilliant
Grain can reduce the ductile-brittle transition temperature towards plasma dignity tungsten, improve heat shock resistance and anti-radiation performance；2) surface Zi Na
Riceization can reduce the difficulty of blocky tungsten processing；3) tungsten surface self-nanocrystallinzation remains the high heat conductance of tungsten.Although material surface
It is more from the method for nanosizing, such as surface mechanical treatment process and unequilibrium thermodynamics method, but tungsten metal surface is directed to from nanometer
Change also in research and trial, because tungsten is the highest metal of fusing point and has big brittleness.What Guo Hongyan was delivered
“Nanostructured laminar tungsten alloy with improved ductility by surface
Mechanical attrition treatment ", in " Scientific Reports " 7 (2017) 1351 article, it was recently reported that
Surface is formd by high-frequency high-speed bullet constant impingement tungsten surface using the mechanical grinding techniques in the mechanical treatment process of surface
It is nanocrystalline and crystallite dimension through-thickness change of gradient to receive micro- Multi-scale model.It is worth mentioning that from focused ion beam
From the point of view of the Multi-scale model section of cutting, occur multiple layering interfaces in gradient-structure layer, integrality is insufficient.Layering is touched with high energy
The effect of hitting is related, and tungsten is bcc metals and has larger brittleness, can not lead under the effect of the strong collision of surface High-velocity Projectiles
It crosses quickly plastic deformation and reaches sustained release stress effect, stress is difficult to transmit the internal formation crackle of cause in tungsten.The method is mainly fitted
Together in the preferable metal and alloy materials of the plasticity such as copper, iron, nickel, titanium, to tungsten material processing, there is also more deficiencies.
Therefore, in order to meet the requirement towards plasma facing materials, the surface for also needing development to have high quality is more
Scale layer tungsten material and process for treating surface.
