Description

Technical Field

[0001] This invention relates to the field of high-temperature alloy technology, and more specifically, to a nickel-based high-temperature wear-resistant alloy and its preparation method. Background Technology

[0002] The anvil insert of a forging hydraulic press is located in the center of the anvil and has a groove. On the bottom surface of the groove are keyways and I-shaped grooves corresponding to the key and I-shaped positioning blocks of the insert. During use, the anvil insert needs to be in direct contact with high-temperature metal, undergoing repeated heating and cooling, and enduring enormous impact forces, making its operating conditions extremely harsh. The anvil insert material is mainly nickel-based alloy, but existing nickel-based alloys have poor high-temperature strength and wear resistance, which can no longer meet future development requirements. Summary of the Invention

[0003] The problem solved by this invention is to improve the high-temperature strength and wear resistance of nickel-based alloys to meet the requirements of anvil inserts for forging hydraulic presses.

[0004] To address the aforementioned problems, this invention provides a method for preparing a nickel-based high-temperature wear-resistant alloy. The nickel-based high-temperature wear-resistant alloy comprises, by weight percentage: C: 0.05% to 0.1%, Cr: 16% to 20%, Co: 8% to 9%, W: 4% to 6%, Fe: 1% to 3%, Al: 5.8% to 6.5%, Ti: 2.9% to 3.2%, Mn: 0.3% to 0.8%, B: 0.010% to 0.02%, Zr: 0.08% to 0.1%, with the balance being Ni. The preparation method of the nickel-based high-temperature wear-resistant alloy includes: Step S1: Melt the alloy raw materials to obtain a melt; Step S2: After the melt is atomized into powder by airflow, it is sieved to obtain alloy powder; Step S3: The alloy powder is subjected to hot isostatic pressing to obtain an alloy ingot; Step S4: After solution treatment, the alloy ingot is cooled to room temperature with water to obtain an intermediate sample; Step S5: After aging the intermediate sample, air-cool it to room temperature to obtain a nickel-based high-temperature wear-resistant alloy.

[0005] Optionally, in step S2, the gas used for airflow atomization powder production is an inert gas.

[0006] Optionally, in step S2, the cooling rate during the airflow atomization powder production process is greater than 100°C / s.

[0007] Optionally, in step S2, the particle size of the alloy powder is 30 μm to 50 μm.

[0008] Optionally, in step S3, the temperature of the hot isostatic pressing treatment is 1170°C to 1190°C, the pressure is 110MPa to 130MPa, and the time is 2h to 4h.

[0009] Optionally, in step S4, the solution treatment temperature is 1160°C to 1200°C, and the time is 5h to 8h.

[0010] Optionally, in step S5, the aging treatment temperature is 840°C to 860°C, and the time is 20h to 30h.

[0011] Optionally, in step S1, the melting is carried out using a vacuum induction melting method.

[0012] The present invention also provides a nickel-based high-temperature wear-resistant alloy, which is prepared by the method described above for preparing nickel-based high-temperature wear-resistant alloys.

[0013] Compared with related technologies, the high-temperature wear-resistant alloy prepared by this invention has a nickel matrix. The nickel matrix can maintain good structural stability and strength at high temperatures. The aluminum (Al) and titanium (Ti) introduced into the alloy are key elements for the formation of the γ' phase, and the strengthening phase is precipitated through subsequent aging treatment, thereby significantly improving the high-temperature strength of the alloy. The chromium (Cr), cobalt (Co), tungsten (W), and iron (Fe) elements introduced into the alloy are dissolved in the matrix, strengthening the matrix through atomic size differences and lattice distortion, thereby further improving the hardness of the alloy and giving it better wear resistance. The trace elements boron (B) and zirconium (Zr) introduced into the alloy can optimize grain boundary strength and improve hot working performance. The manganese (Mn) introduced into the alloy can play an auxiliary role in solid solution strengthening. The composition design of this alloy takes into account both high-temperature strength (strengthened by γ' phase precipitation) and wear resistance (strengthened by solid solution), making it suitable for high-temperature wear environments. Furthermore, this invention uses airflow atomization to obtain alloy powder with uniform composition, high sphericity, and good flowability. The smaller particle size of the alloy powder is then selected for subsequent alloy ingot preparation, which helps reduce internal defects and improve the alloy's density, thereby increasing its strength and hardness. Additionally, the alloy ingot is prepared using hot isostatic pressing, combining sintering and forming. The alloy powder exhibits good flowability under high temperature and pressure, reducing macroscopic segregation and resulting in a finer, more uniform alloy microstructure, significantly improving wear resistance and strength. Solution treatment dissolves the coarse γ' phase into the matrix, preparing for the precipitation of fine, uniform strengthening phases during subsequent aging treatment. Finally, aging treatment precipitates fine, dispersed strengthening phases, further enhancing the alloy's strength. In summary, the nickel-based alloy prepared using the method of this invention possesses high high-temperature strength and excellent wear resistance, meeting the requirements for anvil inserts in forging hydraulic presses.

[0018] like Figure 1 As shown in the embodiment of the present invention, a method for preparing a nickel-based high-temperature wear-resistant alloy is provided. The nickel-based high-temperature wear-resistant alloy comprises, by weight percentage: C: 0.05% to 0.1%, Cr: 16% to 20%, Co: 8% to 9%, W: 4% to 6%, Fe: 1% to 3%, Al: 5.8% to 6.5%, Ti: 2.9% to 3.2%, Mn: 0.3% to 0.8%, B: 0.010% to 0.02%, Zr: 0.08% to 0.1%, with the balance being Ni. The preparation method of the nickel-based high-temperature wear-resistant alloy includes: Step S1: Melt the alloy raw materials to obtain a melt; Step S2: After the melt is atomized into powder by airflow, it is sieved to obtain alloy powder; Step S3: The alloy powder is subjected to hot isostatic pressing to obtain an alloy ingot; Step S4: After solution treatment, the alloy ingot is cooled to room temperature with water to obtain an intermediate sample; Step S5: After aging the intermediate sample, air-cool it to room temperature to obtain a nickel-based high-temperature wear-resistant alloy.

[0019] The high-temperature wear-resistant alloy prepared in this embodiment of the invention is based on a nickel matrix. The nickel matrix maintains good structural stability and strength at high temperatures. Aluminum (Al) and titanium (Ti) introduced into the alloy are key elements for forming the γ' phase, and subsequent aging treatment precipitates strengthening phases, thereby significantly improving the alloy's high-temperature strength. Chromium (Cr), cobalt (Co), tungsten (W), and iron (Fe) introduced into the alloy are dissolved in the matrix, strengthening the matrix through atomic size differences and lattice distortion, thereby further improving the alloy's hardness and giving it excellent wear resistance. The trace elements boron (B) and zirconium (Zr) introduced into the alloy optimize grain boundary strength and improve hot workability. Manganese (Mn) introduced into the alloy plays an auxiliary role in solid solution strengthening. The composition design of this alloy balances high-temperature strength (strengthened by γ' phase precipitation) and wear resistance (strengthened by solid solution), making it suitable for high-temperature wear environments. Furthermore, in this embodiment of the invention, alloy powder with uniform composition, high sphericity, and good flowability is obtained through airflow atomization. The alloy powder with smaller particle size is then screened for subsequent alloy ingot preparation, which helps reduce internal defects and improve the alloy's density, thereby increasing its strength and hardness. Additionally, the alloy ingot is prepared by hot isostatic pressing, combining sintering and forming. The alloy powder exhibits good flowability under high temperature and pressure, reducing macroscopic segregation and resulting in a finer, more uniform alloy microstructure, significantly improving wear resistance and strength. Solution treatment dissolves the coarse γ' phase into the matrix, preparing for the precipitation of fine, uniform strengthening phases during subsequent aging treatment. Finally, aging treatment precipitates fine, dispersed strengthening phases, further enhancing the alloy's strength. In summary, the nickel-based alloy prepared using the method of this embodiment of the invention possesses high high-temperature strength and excellent wear resistance, meeting the requirements for use in anvil inserts of forging hydraulic presses.

[0020] The roles of each element and the design basis in the nickel-based high-temperature wear-resistant alloy prepared in the embodiments of the present invention are as follows: C: Carbon (C) can combine with strong carbide-forming elements in the alloy, such as tungsten and chromium, to form stable carbides. These carbides are dispersed in the alloy matrix, effectively hindering grain growth and dislocation movement, thus improving the high-temperature strength of the alloy. Carbides have extremely high hardness, significantly improving the wear resistance of the alloy. However, excessive C will form a large number of blocky and network carbides, becoming fatigue crack initiation and propagation channels, reducing the mechanical properties of the alloy. Therefore, in this embodiment of the invention, the C content is controlled to be between 0.05% and 0.1%.

[0021] Cr: Cr is an indispensable alloying element in high-temperature alloys. Most of Cr dissolves in the matrix, causing lattice distortion and generating an elastic stress field, thereby achieving solid solution strengthening. Cr can also form MC-type carbides with Ti, and decompose to form M during heat treatment or use. 23 C6 and M6C; Cr dissolved in the matrix can also form a Cr2O3 oxide film, giving the alloy excellent oxidation and corrosion resistance. In this invention, Cr mainly plays a role in solid solution strengthening and improving oxidation and corrosion resistance, but excessive Cr will promote the formation of TCP phase, reduce the plasticity and toughness of the alloy, and increase the cost. Therefore, in the embodiments of this invention, the Cr content is controlled to be 16% to 20%.

[0022] Co: Co dissolves in the matrix, which can reduce the stacking fault energy of the γ phase, promote dislocation slip, and play a solid solution strengthening role. Co can also reduce the solubility of Al and Ti in the matrix, increase the amount of the strengthening γ' phase, and improve strength. However, Co is expensive, and excessive Co can promote the precipitation of harmful phases such as TCP. Therefore, in the embodiments of this invention, the Co content is controlled at 8% to 9%.

[0023] W (W) works synergistically with Cr to form a dense oxide film on the alloy surface, improving corrosion resistance and oxidation resistance. W dissolves in the matrix, providing solid solution strengthening. W significantly reduces the dislocation energy of the γ matrix, thereby improving the alloy's creep performance. Furthermore, W combines with C to form MC-type carbides, pinning grain boundaries and dislocations, inhibiting grain coarsening at high temperatures, and maintaining the alloy's mechanical properties in high-temperature environments, ensuring its ability to withstand high loads and frictional wear. However, excessive W promotes the precipitation of the TCP phase, affecting the alloy's mechanical properties and increasing raw material costs. Therefore, in this embodiment of the invention, the W content is controlled to be 4% to 6%.

[0024] Fe: The addition of Fe to nickel-based superalloys can not only effectively reduce costs but also lower stacking fault energy, hinder dislocation movement, and provide solid solution strengthening. Excessive Fe promotes the precipitation of brittle phases, inhibits the precipitation of strengthening phases, and reduces the alloy's mechanical properties. Therefore, in this embodiment of the invention, the Fe content is controlled to be between 1% and 3%.

[0025] Al: Al is one of the main constituent elements of the γ' phase in the alloy. It enhances the alloy's performance through precipitation strengthening and simultaneously alters the solubility of elements in the γ' phase, further optimizing the strengthening effect. Al promotes the formation of a dense oxide film (such as Al2O3), effectively isolating oxygen and corrosive media, and significantly improving the alloy's stability in high-temperature oxidizing environments. However, excessive Al can cause the precipitation of harmful phases, impairing the alloy's ductility and toughness. Therefore, in this embodiment of the invention, the Al content is controlled to be between 5.8% and 6.5%.

[0026] Ti: In high-temperature alloys, 90% of the Ti element enters the γ' phase, replacing Al atoms to form Ni3(Al,Ti), improving the alloy's room temperature and high temperature strength. Ti is a major forming element of MC-type carbides (such as TiC), which can pin grain boundaries and inhibit grain coarsening. However, excessive Ti can cause changes in the precipitation morphology of grain boundary carbides, weakening grain boundaries and precipitating lamellar brittle phases. These phases are distributed along the grain boundaries, significantly reducing the alloy's plasticity and toughness. Therefore, in the embodiments of this invention, the Ti element content is controlled at 2.9% to 3.2%.

[0027] Mn: An appropriate amount of Mn can refine grains, stabilize austenite, and promote the dispersed distribution of carbides. However, excessive Mn will segregate at grain boundaries, weaken grain boundary bonding, promote the precipitation of harmful phases, and reduce mechanical properties. Therefore, in this embodiment of the invention, the Mn content is controlled to be 0.3% to 0.8%.

[0028] B: A suitable amount of boron accumulates at grain boundaries, increasing grain boundary bonding strength; borides are distributed at grain boundaries in granular or blocky form, preventing grain boundary slip and inhibiting the connection and expansion of grain boundary voids; however, excessive boron will exacerbate grain boundary embrittlement, promote the precipitation of TCP phase, and reduce mechanical properties. Therefore, in the embodiments of this invention, the boron content is controlled to be 0.010% to 0.02%.

[0029] Zr: Zr segregates at grain boundaries, reducing grain boundary defects, increasing grain boundary bonding strength, decreasing grain boundary diffusion rate, and strengthening grain boundaries. Zr can also lower interfacial energy, alter the morphology and size of grain boundary phases, effectively preventing grains from sliding along grain boundaries and improving the service life of the alloy. However, excessive Zr can form Zr-O inclusions, reducing grain boundary strength, promoting the precipitation of harmful phases, and decreasing mechanical properties. Therefore, in this embodiment of the invention, the Zr content is controlled to be between 0.08% and 0.1%.

[0031] In some embodiments of the present invention, in step S2, the particle size of the alloy powder is 30 μm to 50 μm. In this embodiment, by controlling the particle size of the alloy powder to be smaller, the density of the alloy is increased, thereby increasing the strength of the alloy.
