Embodiment
Technical scheme is described in detail below in conjunction with the accompanying drawings：
In order to meet the security reliability of MSR welding structural element, the present invention proposes one kind and is used for anti-fused salt corrosion
The solder of nickel base superalloy fusion welding, its component (percentage by weight) are specific as follows：
C content is controlled between 0.03~0.06%, is preferably controlled between 0.05~0.06%, within the range
C makes weld seam have preferable tough matching.C content is higher, can increase the intensity of weld seam, but plasticity can decrease, in addition, such as
Fruit C content is too big, can make to form substantial amounts of carbide in weld seam, reduces seam organization stability, carbon content is too low, can make weld seam
Low strength.
Mn content is controlled between 0.04~0.10%, is preferably controlled between 0.5~0.8%, and Mn is mainly as de-
Oxygen agent and desulfurizing agent, it can be smelted in wlding and deoxidation and desulfurization are carried out in welding process, reduce the impurity element in weld seam；
In addition, Mn elements are readily collected in dendrite circle, can play a part of strengthening dendrite circle.
Si content is preferably controlled between 0.3~0.5%, and to prevent the oxidation of weld seam, stable base ensures to weld silicon
Stitch intensity, moreover it is possible to improve the pattern of Carbide Precipitation phase, quantity and distribution situation in weld seam.As silicone content ＜ 0.3%, weld seam
More unstable M can be formed2C-type carbide, stable M6C-type carbide is less, M2C-type carbide can occur at high temperature
Decompose, influence the elevated temperature strength of weld seam；When silicone content is 0.5~1.0%, the welding performance of steel can be reduced, it is easy in welding
Low melting point silicate is generated, increases the mobility of slag and fusion, influences welding quality；It is by optimal control silicone content
0.3~0.5%, weld seam can be formed to stablize M6Based on c-type carbide, it is less likely to occur to decompose under high-temperature service, ensures it
High-temperature service intensity.
Cu can easily cause rich Cu clusters to separate out with improving welding property, but under neutron irradiation, damage weld seam it is anti-in
Sub- irradiation behaviour；Co can significantly improve the creep strength and plasticity of alloy as solution strengthening element.But because solder is molten
In the welding application of salt pile structure part, high neutron irradiation can be subjected to, decaying is60Co, this is a kind of radioactive material of long half-lift
Matter, while gamma-rays is accompanied by, it is larger to environmental hazard.In summary information, the copper coin in solder of the present invention should strictly be controlled
Element, Co elements should control content that rationally may be low in regulation.Cu element weight percents in solder of the present invention are defined to≤
0.10%, Co element weight percent are defined to≤0.20%.
P and S is impurity element, weldability is deteriorated, and reduces plastic property of weld bead, in addition, easily forming segregation in weld seam, is damaged
The anti-neutron irradiation performance of evil weld seam.P and S fully belongs to harmful element, is preferably occurred without in theory in solder of the present invention, still
Crossing the control of low content can cause cost to increase.Through comprehensive consideration, P and S elements require that control is in solder of the present invention：P≤
0.015%, S≤0.015%, S+P≤0.02%.
Rare earth element (Re) can be with the low melting point such as phosphorus, arsenic, tin, antimony, bismuth, lead harmful element phase separation in steel, both can be with
The higher compound of low melting point is formed with these impurity, can also suppress these segregations being mixed on crystal boundary, play catharsis,
Reduce the impurity in weld seam.Rare earth easily generates the oxysulfide of rare earth, forms complex inclusion or rare earth silicate
Compound, their fusing point is high and highly stable, can control the pattern of field trash.Rare earth element can improve weld seam intensity and
Toughness, the creep rupture strength of weld seam is improved, when the control of rare earth element content is 0.01~0.05%, the anti-height of weld seam can also be improved
Warm oxidation susceptibility, but when rare earth element content more than 0.05%, oxidation resistance reduces on the contrary, and rare earth element price compared with
It is high.Therefore the rare earth element percentage by weight in solder of the present invention is defined to 0.01~0.05%.
Fe content is controlled between 1.0~5.0%, and Fe elements add mainly as accompanying element, can be with replacing section
Nickel with reduce cost and improve waste utilization rate.
Cr content is controlled between 6.0~8.0%, and Cr within the range is effectively improved in oxidizing corrosion medium
In decay resistance key element, and high temperature oxidation resistance can be improved.But in MSR Service Environment, weld seam is in height
Corrosion mechanism in temperature molten salt, mainly Cr elements are diffused into fused salt in large quantities.In order to reduce fused salt corrosion, preferably control
Cr elements are 6.0%.
Mo content is controlled between 12.0~18.0%, preferably between 16.0~18.0%, molybdenum within the range
Mainly as strong solution strengthening element, its atomic radius is larger, makes lattice that big distortion occur after solid solution, significantly strengthens γ bases
Body, improve the elevated temperature strength of alloy.
Al, Ti are controlled elements in solder of the present invention, and when the increase of both constituent contents, weld seam tends to form γ '
Precipitated phase, it is unfavorable to alloy property because γ ' precipitated phases can grow up failure under the high temperature conditions for a long time.Nb shapes in weld seam
Into tiny carbide, austenite recrystallization can be prevented in heating process with pinning crystal boundary, delay to recrystallize the crystalline substance of austenite
Grain length is big, is advantageous to the control in wlding (the especially real core or flux-cored wire of small diameter) preparation process, and the change formed
Compound can be used as equiax crystal, refine the tissue of weld seam, improve the intensity of weld seam, in addition, Nb elements are added in solder, can
To strengthen the embrittling effect of weld seam resistance fission product tellurium.Al and Ti elements require that control is in solder of the present invention：Al≤
0.3%, Ti≤0.2%, and Nb content is controlled between 1.0~2.0%, and Ti+Nb+Al≤2%.
In order to verify effect of the present invention, prepared using the solder of four kinds of different componentsSolid core welding wire, and utilize institute
