In a first aspect, the present application provides a nickel-based superalloy foil easy to punch forming, please refer to a microstructure diagram of the nickel-based superalloy foil easy to punch forming shown in fig. 1, the uniformity of the microstructure is good, and the chemical components of the nickel-based superalloy foil include: C. cr, co, W, mo, al, ti, fe, B, ce, zr and Ni; wherein, the mass fraction of the material is calculated,
the content of C is 0.02-0.1%, and the content of Cr is 17.0-20.5%; the content of Co is 8.2-10.0%; the alloy comprises 0.5-2.5% of W, 1.2-3.5% of Mo, 4.3-7.0% of Al, 1.0-2.8% of Ti, 18.2-21.8% of Fe, 0.002-0.01% of B, 0.002-0.015% of Ce and 0.008-0.05% of Zr.
In the embodiment of the application, the chemical components of the nickel-based superalloy foil material easy to be stamped and formed have the following functions:
cr: mainly exists in a nickel-based superalloy matrix in a solid solution state, has the main functions of improving the oxidation resistance and the hot corrosion resistance of the alloy, has a certain solid solution strengthening effect, and can be combined with C to form granular M distributed along crystals 23 C 6 And plays a role in strengthening grain boundaries. However, when the Cr content is too high, the structural stability and the forming processability of the alloy are reduced, and the alloy in the embodiment of the application is mainly used as a honeycomb seal structural member material, and has higher requirements on the forming processability of the alloy, so that the Cr content is allowed to be lower than that of a common nickel-based wrought superalloy, and relatively high forming processability and structural stability are replaced. Specifically, the Cr content may be 17.0%, 17.5%, 18.0%, 18.5%, 19.0%, 19.5%, 20.0%, 20.5%, etc.
Fe: the Fe element mainly replaces Ni and promotes the alloyThe phase precipitation can reduce the alloy cost and improve the corrosion resistance of the alloy. With a further increase in Fe content, not only is +.>The precipitation of phases also promotes the precipitation of beta and the like in the alloy, thereby improving the workability and weldability of the alloy, but when the Fe content is too high, a large amount of sulfide and oxide inclusions may be formed with O, S in the alloy, forming a crack source. Specifically, the content of Fe may be 18.2%, 18.5%, 19.0%, 19.5%, 20.0%, 20.5%, 21.0%, 21.5%, 21.8%, or the like.
W and Mo: all are solid solution strengthening elements, so that the alloy strength can be improved; however, the excessive content can cause excessive precipitation phase quantity and grain refinement, greatly reduce the high-temperature tensile property of the alloy, and the W element can also form a large amount of carbide, so that the solid solution strengthening effect of the element is weakened, and the machinability of the alloy is reduced. Specifically, the content of W may be 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, etc., and the content of Mo may be 1.2%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, etc.
Co: mainly is in solid solution inIn the matrix, the solution strengthening effect is achieved, the stacking fault energy of the matrix is reduced, and the solubility of Al and Ti in the matrix is reduced, so that the +.>The number of phases is increased->The dissolution temperature of the phase, thereby significantly improving the plasticity and workability of the alloy. Specifically, the content of Co may be 8.2%, 8.5%, 8.8%, 9.0%, 9.2%, 9.5%, 9.8%, 10.0%, etc.
Al and Ti: al and Ti are formed ofThe main elements of the phase can greatly improve the precipitation strengthening effect of the alloy. At the same time, the addition of Al element can form Al on the surface of the alloy 2 O 3 The protective film is beneficial to improving the oxidation resistance of the alloy; the Ti element is a strong carbonitride element, can form Ti (CN), plays a role in strengthening alloy, and meanwhile, the addition of Ti is beneficial to improving corrosion resistance. Increased Al+Ti content, < >>The phase size is reduced, the room temperature and high temperature tensile strength of the alloy are improved, the larger the Ti/Al value is, the higher the inversion domain boundary energy is, but too high Al and Ti can separate out harmful beta phase, which is not beneficial to tissue stabilization. Specifically, the content of Al may be 4.3%, 4.5%, 5.0%, 5.5%, 6.0%, 6.5%, 7.0%, etc., and the content of Ti may be 1.0%, 1.5%, 2.0%, 2.5%, 2.8%, etc.
B: the grain boundary strengthening element can increase the plasticity of the alloy, is beneficial to the coordinated deformation of the grain boundary in the hot working process, and can improve the oxidation resistance and creep resistance of the alloy. However, the B content is too high, so that massive boride is easy to form at the grain boundary, and the mechanical property of the alloy is not facilitated. Specifically, the content of B may be 0.002%, 0.005%, 0.007%, 0.009%, 0.01%, etc.
Ce and Zr: the Ce and Zr elements can play a good role in deoxidization, desulfurization and degassing in the alloy smelting process, purify and strengthen grain boundaries, and improve the processing performance of the alloy; the alloy can also be used as micro alloying elements to be biased to grain boundaries to play a role in strengthening the grain boundaries; in addition, ce is used as an active element, so that the oxidation resistance of the alloy can be improved, and the surface stability can be improved. The Zr element can also improve the low-temperature toughness of steel, eliminate aging phenomenon, improve the stamping performance of alloy, and excessive zirconium content can promote element dendrite segregation, thereby changing the form and the type of a grain boundary precipitated phase, being unfavorable for the stable structure of alloy, and secondly, zirconium can also increase the lattice distortion between a granular precipitated phase and a matrix, so that the defects of micro-porosity and the like around grains are increased. Too high rare earth elements can form large amounts of large-particle rare earth compounds at grain boundaries, which can adversely affect the properties of the alloy. Specifically, the Ce content may be 0.002%, 0.004%, 0.006%, 0.008%, 0.010%, 0.012%, 0.014%, 0.015%, etc., and the Zr content may be 0.008%, 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, etc.
