A,668 (2016) 137.); 2. the alloy is a high-W low-Cr system, a continuous compact NiCr2O4 oxide film cannot be formed at high temperature, so that the high-temperature oxidation resistance of the alloy is poor (Corros.

A preparation method of a high-strength high-plasticity corrosion-resistant nickel-based alloy comprises the following steps:
s1, casting master alloy by adopting a vacuum induction furnace;
s2, homogenizing the cast master alloy;
and S3, performing heat treatment.
In the step S1, a master alloy is cast by adopting a vacuum induction furnace.
In the step S2, the cast master alloy is subjected to homogenization treatment, the temperature of the homogenization treatment is controlled to be 1050-1250 ℃, and the time of the homogenization treatment is controlled to be 5-30 hours.

The percentages appearing in the invention are all mass percentages.
According to the research, since the inner wall and the outer wall of the high-temperature molten salt environment structure alloy are respectively contacted with high-temperature molten salt and air, the high-temperature molten salt environment structure alloy needs to have excellent mechanical properties, and also needs to resist molten salt corrosion and high-temperature oxidation, the Ni- (26-28) W-6Cr alloy has excellent mechanical properties at room temperature and 850 ℃, but the strength and plasticity of the high-temperature molten salt environment structure alloy are poor in the temperature range of 650-750 ℃, through the research on the microstructure of the tensile fracture of the Ni- (26-28) W-6Cr alloy at different temperatures, the strength of the grain boundary of the Ni- (26-28) W-6Cr alloy in a medium-temperature region (650-750 ℃) is weak and cannot accommodate excessive dislocation, a small amount of dislocation plug in the stress loading process can lead to grain boundary fracture failure, B is a grain boundary strengthening element commonly used in the high-temperature alloy, and the proper amount of B is added to strengthen the grain boundary of the Ni- (26-28) W-6Cr alloy, so that the medium-temperature strength and plasticity of the alloy are effectively improved.
In order to ensure that the Ni- (26-28) W-6Cr alloy has good molten salt corrosion resistance, the Cr content in the alloy is far lower than the critical value of forming a continuous compact Cr2O3 oxide film in the nickel-based alloy, the main phases of the oxide film of the Ni- (26-28) W-6Cr alloy at 850 ℃ are NiWO4 and CrWO4, a large number of oxygen vacancies are contained in the two oxides, a channel (Corros. Sci.,149 (2019) 87.) can be provided for the diffusion of oxygen into an alloy matrix, the research shows that the valence state of Ni in the NiWO4 is +2, and according to the Hauffe-Wagner theory, if the doping valence state is higher than the element of +2 in the NiWO4, the doping element can replace the Ni < 2+ > in the NiWO4 to ensure that the Ni is positive valence, so that the diffusion of cations is blocked, the high-temperature oxidation resistance of the alloy is improved, the valence state of B is generally +4 and +6, and the proper amount of B doped in the Ni- (26-28) W-6Cr alloy can improve the high-temperature oxidation resistance of the alloy.
Referring to FIG. 2, FIG. 2 is a calculation result of JMatPro 7.0 (TTNi-8 database), and when the B addition amount exceeds 0.05wt.% (500 ppm) in the Ni-26W-6Cr-0.1Si-0.45Mn-0.02C alloy system, a large amount of M3B2 phase is generated, which is detrimental to the mechanical properties of the alloy, so that the B addition amount is controlled within 0.05 wt.%.
In the present invention, the high-strength high-plasticity corrosion-resistant nickel-base alloy according to the present invention will be further described in detail by examples 1, 2, 3, 4 and 5, within the above-mentioned composition ranges:
the alloy is obtained by the following steps: the chemical composition of the alloy obtained by smelting pure B (99.99%) and Ni-26W-6Cr master alloy (composition see example 1) in a vacuum induction furnace in a certain proportion, followed by heat treatment and processing is referred to in Table 1, and the chemical composition of the Ni-26W-6Cr master alloy (composition of Ni-26W-6Cr see example 1) is also listed in Table 1 for embodying the properties of the alloy of the present invention;

| Example 5 | Bal. | 27.3 | 6.6 | 0.21 | 0.32 | 0.041 | 35 |
Referring to fig. 3, fig. 3 shows the microstructure of example 3, which is the microstructure of the bar after forging the ingot subjected to the homogenization treatment at 1200 ℃ at 1180 ℃, and it can be seen that the microstructure of the alloy is uniform and the fine precipitated phases are uniformly dispersed in the alloy matrix.
Referring to Table 2, table 2 shows the 650 ℃ tensile property data of examples 1-5, the strength and elongation of the alloy are improved simultaneously with increasing B content to 224ppm, especially the elongation is improved from 12.1% without B to 36.5%, and when B content is further increased to 432ppm, the yield strength of the alloy is increased but the tensile strength and elongation are reduced, referring to FIG. 4, the (a) and (B) in FIG. 4 are the 650 ℃ tensile fracture morphology of example 1 and example 2, respectively, and are typical along-grain brittle fracture morphology, the (c) and (d) in FIG. 4 are the tensile fracture morphology of example 3 and example 4, and when B content reaches 224ppm or more, the fracture of example 3 and example 4 is a ductile pit morphology, indicating that adding B can significantly improve the medium temperature plasticity of Ni- (26-28) W-6Cr alloy.
