20% one such or two kinds and above element institute partial replacement.It is strong containing the following one or two kinds of and above crystal boundary in alloy
Change element: C 0.001-1.0%, B 0.001-1.0%, Y 0.001-1.0%, La or Ce rare earth element 0.001-1.0%, Mg
0.001-1.0%, Ca 0.001-1.0%.
The design considerations of above-mentioned chemical component is as follows:
Ni: matrix element guarantees there is good combination of strength and toughness while obtaining high-density Ni W solid solution, and Ni can
W to be solid-solution in opposite low-melting-point metal, it is possibly realized so that preparing high density tungsten alloy by the way of melting.By
In melting be not present consistency the problem of, and can by the method for forging refine crystal grain, can by way of solid solution-precipitation with
Second-phase strength, such as Ni4W, Ni3 (Ti, Al), NiW, Ni3Nb hardening constituent, therefore, mechanical property can greatly improve.
Co: matrix element can be exchanged with Ni, can be used in combination or be used alone with Ni, W can be solid-solution in
In opposite low-melting-point metal, it is possibly realized so that preparing heavy alloy by the way of melting.But W solid solubility in Co
It not as good as the solid solubility in Ni, therefore is usually NiCo of the solid solution content of raising W frequently with Ni base or based on Ni compound.Co
It can promote the precipitation of precipitated phase, while in Co base high density kinetic energy alloy, Co will form the equal progress of Co3W, Co3 (Al, W)
Precipitation strength.
W: being to mention highdensity essential element, be solid-solubilized in Ni matrix, not only improve density, can easily pass through Ni4W, NiW etc.
Precipitation is strengthened, and theoretically the higher the better for W content, but W solid solubility in Ni is limited, obtains duplex structure when more than 40%,
Then since fusing point is excessively high when more than 75%, the technique that can only use powder metallurgy, if too low less than 20%, density is not achieved
10.0g/cm3, therefore in this patent range, W content is limited to 20-75%.
Nb: a certain amount of Nb is added can be precipitated Ni3Nb phase in ag(e)ing process, can effectively promote mechanical property, but excessive meeting
It is serious to reduce plasticity and toughness, therefore present invention control is within 0-20%.
Ta: being preferably to mention highdensity element, and effect is suitable with W, but since Ta is strategic resource, expensive, special
Be not Ta in smelting caused by pollution problem limit the use of Ta, therefore the present invention by the content control of Ta 0-20% with
It is interior.
The effect of Hf:Hf is similar to Ta, can also be improved density, but its strengthening effect is weaker, simultaneously because it is rare, therefore
The control of Hf content is in 0-10% in the present invention.
Ti: a certain amount of Ti is added can be precipitated γ ' phase in ag(e)ing process, can effectively promote mechanical property, but excessively can be tight
Plasticity and toughness are reduced again, therefore present invention control is within 0-10%.
Al: a certain amount of Al is added can be precipitated γ ' phase in ag(e)ing process, can effectively promote mechanical property, but excessively can be tight
Plasticity and toughness are reduced again, therefore present invention control is within 0-10%.
The effect of V:V is similar to Nb and L1B2 type hardening constituent component, i.e., improves intensity by being precipitated, but V's is strong
Change effect and be not so good as Nb, therefore the content of V is controlled in 0-10% in the present invention.
The effect of Zr:Zr is similar to V, both precipitation strength, but Zr can also can be participated in by substitute mode with solution strengthening
Effect it is smaller, while Zr addition influence other essential elements solubility product, therefore, the present invention in Zr content control exists
0-10%.
Mo:Mo and W is to exchange element, and the two can be exchanged infinitely substantially, but the density of Mo is low, atomic radius is small, especially
It is that the two exchanges Mo:W as 1:2, the two exchanges the raising that can seriously affect density, therefore Mo content of the present invention control is in 0-
20%.
Cu: can reduce the solid solubility of the elements such as W, Mo in the base, and precipitated phase is promoted to be precipitated, but Cu too high levels may be
Compound between the hard brittle metal of large scale is formed in liquid phase, forging or when extrusion blooming form crackle, the application content 0-5%；
C:C is boundary-strengthening element, by C element in the enrichment of crystal boundary, can significantly reduce other harmful elements in crystalline substance
The enrichment on boundary, to improve grain-boundary strength, by with W, Nb etc., which forms primary carbide, can effectively facilitate solidification forming core, pass through
Refinement and uniform arborescent structure improve the strong plasticity of tissue, have improvement result to hot-working character, can simultaneously serve as crystal grain
Fining agent thinning microstructure, but the excessively high intensity that not only reduces of C content more seriously reduces plasticity, therefore C content of the present invention control exists
0.001-1.0%.
B:B is boundary-strengthening element, by B element in the enrichment of crystal boundary, can significantly reduce other harmful elements in crystalline substance
The enrichment on boundary improves thermoplasticity to improve grain-boundary strength, hot-working character is improved, but the control of B content is critically important, when B contains
Measure excessively high, plasticity can be reduced instead, endanger hot-working character, thus in the present invention B content control in 0.001-1.0%.
Y:Y both can be used as deoxidier use and be de-gassed and refine crystal grain, can also be improved crystal boundary bond strength, simultaneously
Deoxidation products is to solidified structure state is improved, and the control of Y content is in 0.001-1.0% in the present invention.
La or Ce and other rare earth elements: La or Ce and other rare earth elements are mainly to inclusion conditioning, while as de-
Oxygen agent uses, and a small amount of also La or Ce and other rare earth elements can also be used as solidified structure fining agent and grain refiner and make
With, while also assisting in precipitated phase precipitation, but quantity can excessively seriously affect the reduction of plasticity and toughness, thus in the present invention La or Ce and
Other rare earth elements 0.001-1.0%.
The effect of Mg:Mg is similar to B, participates in purification to crystal boundary, while can also be used as deoxidier and crystal grain is thin
Agent uses, and the content of Mg is controlled in 0.001-1.0% in the present invention.
The effect of Ca:Ca is similar to B, participates in purification to crystal boundary, while can also be used as deoxidier and crystal grain is thin
Agent uses, and the content of Ca is controlled in 0.001-1.0% in the present invention.
Fe:Fe is matrix element, be can be interchanged with Ni and Co, but Fe significantly reduces the solid solubility of elements such as w, while Fe meeting
It is more to reduce objectionable impurities elements in density, especially Fe, is affected to industrialized trial-production, therefore the content of Fe of the present invention
Control is in 0-30%.
Cr: matrix element exchange can be participated in, while being participated in by the Ni or Co that substitute mode substitutes L1B2 type hardening constituent
Precipitation strength, it may have solid solution strengthening effect, but Cr seriously affects density, therefore Cr content is controlled in 0-20% in the present invention.
Ir:Ir is the element that can preferably exchange in most of alloys with Fe race element, and the influence to performance is smaller,
But due to the scarcity of Ir, the content of Ir is controlled in 0-50% in the present invention.
Re and Ru:Re and Ru can be exchanged with matrix element, but Re and Ru are affected to performance, influence intensity, together
When due to resource scarcity, the present invention in Re and Ru controlled respectively in 0-20% and 0-20%.
