Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of high-temperature alloys, and in particular to an aging-strengthened nickel-based high-temperature alloy material and a preparation method thereof. Background Art
[0002] GH4099 is an age-hardened nickel-based high-temperature alloy. Its main components include nickel, cobalt, tungsten, molybdenum, aluminum and titanium. By adding these elements, GH4099 alloy achieves excellent high-temperature resistance and good thermal stability. In particular, aluminum and titanium, as age-hardening elements, react chemically with the matrix at high temperatures to form fine precipitates. These precipitates gradually precipitate and disperse during the cooling process of the alloy, effectively hindering the movement of dislocations, thereby achieving age-hardening of the alloy. GH4099 alloy is a high-temperature strong material with excellent high-temperature performance. The operating temperature can reach 1000°C, and it can still maintain good oxidation resistance, creep resistance and fatigue resistance at high temperatures. These characteristics make GH4099 alloy have extremely high application value in high-temperature environments such as aerospace, especially in key components such as aircraft engine combustion chamber parts, reinforcement ribs and aircraft fixtures. It shows great application potential.
[0003] The grain size of GH4099 alloy bars produced by the existing process in the hot-rolled state is between 9.0 and 10.0 on average, and the grain size of the final product is between 9.0 and 2.0 on average, with the mass of 2.0 accounting for about 25%. The overall sample has fine grain bands and uneven grain size distribution. The grain size of GH4099 alloy bars is excessively refined or the band structure is uneven, which will cause high-temperature endurance notch sensitivity, and eventually lead to breaking due to insufficient high-temperature endurance time, which does not meet the standard requirements. Summary of the invention
[0004] In view of the above problems, the present invention provides an age-hardened nickel-based high-temperature alloy material and a preparation method thereof. By adding a preheating treatment step after rolling and before machining, the grain size uniformity of the age-hardened nickel-based high-temperature alloy material is improved, and the high-temperature endurance time of the age-hardened nickel-based high-temperature alloy material is greatly increased.
[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: In a first aspect, the present invention provides a method for preparing an aging-hardened nickel-based high-temperature alloy material, comprising the following steps: S1, subjecting the raw materials to vacuum induction melting, electroslag remelting, rapid forging and rolling in sequence to obtain rolled steel; S2, preheating the rolled steel at 1110° C.-1150° C., and machining the rolled steel to obtain an aging-hardened nickel-based high-temperature alloy material.
[0006] Compared with the prior art, the preparation method of the age-hardened nickel-based high-temperature alloy material provided by the present invention utilizes a dual process (vacuum induction melting + electroslag remelting) for smelting, and then undergoes rapid forging to open the blank and roll forming, and the obtained rolled steel is preheated at a specific temperature before machining, thereby obtaining an age-hardened nickel-based high-temperature alloy material with excellent mechanical properties, improving the structural uniformity of the grain size of the existing age-hardened nickel-based high-temperature alloy material, and greatly improving the high-temperature endurance time of the age-hardened nickel-based high-temperature alloy material, which has a good market development prospect. The results of the embodiment show that the grain size of the age-hardened nickel-based high-temperature alloy material obtained after preheating treatment is 3.0 to 4.5, and the high-temperature endurance time of the age-hardened nickel-based high-temperature alloy material is extended to more than 55 hours, and can reach up to more than 97 hours.
[0007] The present invention has accidentally discovered through a lot of time that when preparing age-hardened nickel-based high-temperature alloy materials, by adding a preheating treatment step after rolling and before machining, the uniformity of the grain size of the age-hardened nickel-based high-temperature alloy materials can be effectively improved, and its high-temperature endurance time can be greatly increased. In addition, the temperature of the preheating treatment has a significant impact on the uniformity of the grain size and the high-temperature endurance time. If the preheating treatment temperature is too low, the speed of grain size recovery and recrystallization will slow down, and the time required will be longer; if the preheating treatment temperature is too high, it will cause the grains to grow too fast, and the outer and central grains of the alloy material will be mixed, that is, the grain size of the outer ring of the alloy material is already coarse, and the central part has just begun to recover and recrystallize; and the higher the preheating treatment temperature, the faster the grain size will grow, and if the grains are too coarse, other properties (such as room temperature strength and plasticity) will be unqualified.
[0008] Preferably, the age-hardened nickel-based high-temperature alloy material is GH4099 alloy material.
[0009] Preferably, the GH4099 alloy material includes the following chemical components in mass percentage: Cr 17.0%~20.0%, W 5.0%~7.0%, Mo 3.5%~4.5%, Ti 1.1%~1.5%, Al 1.7%~2.3%, Co 5.0%~8.0%, C≤0.08%, Fe≤2.0%, Mg≤0.01%, Si≤0.5%, Mn≤0.4%, B≤0.005%, Ce≤0.02%, Cu≤0.25%, S≤0.015%, P≤0.015%, and the balance is Ni and unavoidable impurities.
[0010] Preferably, S1 comprises the following steps: S1-1, vacuum induction melting: adding raw materials into a vacuum induction furnace, melting and refining, tapping, pouring, and obtaining electrode blanks; The raw materials include 50wt% to 60wt% of aging-strengthened nickel-based high-temperature alloy return material; during the material addition and conditioning process, C is not added simultaneously with Cr, Mo, W or Ti; S1-2, electroslag remelting: placing the electrode blank into an electroslag crystallizer, adding electroslag remelting slag, introducing inert gas, and performing electroslag remelting to obtain an electroslag ingot; S1-3, rapid forging and blanking: forging the electroslag ingot at 1150° C. to 1180° C., with a deformation amount of 32% to 40% per fire, to obtain a forged steel billet; S1-4, rolling: rolling the forged steel billet at 1140° C. to 1170° C. to obtain the rolled steel.
[0011] The present invention uses high return ratio age-hardened nickel-based high-temperature alloy return materials as raw materials. Each element is not easy to segregate during the smelting process, and the smelting cost is greatly saved. During the process of adding and seasoning, C easily forms compounds with Cr, Mo, W and Ti respectively, and is not easy to be removed, thereby increasing the content of inclusions in the subsequent material, which has an adverse effect on the final performance of the age-hardened nickel-based high-temperature alloy material. The present invention can ensure sufficient deformation during the forging process and prevent forging cracking by limiting the forging temperature and deformation of each fire, thereby improving the yield rate of age-hardened nickel-based high-temperature alloy materials. The inventor found through a large number of experiments that when the deformation of each fire is less than 30%, insufficient deformation will result; when the deformation of each fire is greater than 40%, the alloy material is very likely to have a risk of fracture, and the yield rate is greatly reduced.
[0012] Further preferably, in S1-1, the aging-hardened nickel-based high-temperature alloy return material is GH4099 alloy return material, more preferably waste GH4099 alloy return material.
[0013] Further preferably, in S1-1, the melting temperature is 1450°C~1500°C, the refining temperature is 1500°C~1550°C, the refining vacuum degree is ≤3Pa, the vacuum induction melting time is 80min~100min, and the tapping temperature is 1420°C~1500°C.
[0014] For example, in S1-1, the diameter of the electrode blank is 250 mm.
[0015] Further preferably, in S1-1, the electrode blank comprises the following chemical components in mass percentage: Cr 17.5%~19.5%, W 5.0%~7.0%, Mo 3.5%~4.5%, Ti 1.1%~1.35%, Al 2.05%~2.25%, Co 5.5%~7.5%, C0.03%~0.05%, Fe≤2.0%, Mg≤0.01%, Si≤0.5%, Mn≤0.4%, B≤0.005%, Ce≤0.02%, Cu≤0.2%, S≤0.01%, P≤0.01%, and the balance is Ni and unavoidable impurities.
[0016] For example, in S1-1, after pouring and solidification, grinding or flattening is required to obtain an electrode blank.
[0017] Further preferably, in S1-2, the electroslag remelting slag comprises the following raw material components in percentage by weight: CaF 2 55%~65%,Al 2 O 3 18%~22%, CaO 8.5%~11.5% and MgO 8.5%~11.5%.
[0018] Further preferably, in S1-2, the melting rate of the electroslag remelting is 2.8 kg / min~3.2 kg / min.
[0019] For example, in S1-2, the diameter of the electroslag crystallizer is 360 mm.
[0020] For example, in S1-2, the inert gas is argon.
[0021] For example, in S1-2, the diameter of the electroslag ingot is 360 mm.
[0022] Further preferably, in S1-3, the forging time is 3h~4h.
[0023] Further preferably, in S1-3, the diameter of the forged steel billet is 145 mm to 155 mm.
[0024] For example, in S1-3, after forging, polishing and cutting are also included.
[0025] Further preferably, in S1-4, the rolling temperature is 1150°C to 1160°C, and the rolling time is 1h to 1.5h.
[0026] Further preferably, in S1-4, the diameter of the rolled steel is 10 mm to 70 mm.
[0027] Preferably, in S2, the temperature of the preheat treatment is 1120°C to 1140°C, more preferably 1130°C.
[0028] Preferably, in S2, the preheating treatment time is 0.5 h to 2 h, more preferably 1 h to 1.5 h.
[0029] The present invention has found through a large number of experiments that if the preheating treatment time is too short, the grain size recovery and recrystallization of the alloy material will be insufficient, that is, the grain size of the outer ring has recovered and recrystallized, but the core has not started, resulting in mixed crystals; if the holding time is too long, it will not only waste energy, but also cause the grain size of the alloy material to be too coarse, causing other performance indicators (such as room temperature strength and plasticity) to be unqualified.
[0030] Preferably, after the rolling is completed, the obtained rolled steel is directly sent to a preheating furnace for the preheating treatment, and the charging furnace temperature is ≥800°C.
[0031] The present invention does not need to cool after rolling, and the rolled steel is loaded into a furnace for preheating treatment before the temperature of the rolled steel cools down, so that the rolled steel is quickly heated to the preheating temperature, making the grain size of the alloy material more uniform.
[0032] Preferably, in S2, air cooling is also included after the preheating treatment and before the machining.
[0033] For example, in S2, before machining, the slice is inspected, and machining is performed only after the inspection is qualified.
