Description:
Nickel-based superalloys refer to high-temperature alloys with high stren↔gth and good resistance to oxidation and gas corrosion in the range of 650-1000 ° C with nickel✘ as the matrix (generally greater than 50%). Nickel-based superalloys (hereinafter refeαrred to as nickel-based alloys) were developed in the late 1930s. In 1941, the United Kingdom first produced the Ni-based alloy Nimonic 75 (Ni-20Cr-0.4Ti); in order t↓o increase the creep strength and added aluminum, Nimonic 80 (Ni-20Cr-2.5Ti-1.3Al) was developed. In the mid-1940s, the Soviet✘ Union in the late 1940s, China also developed nickel-based alloys in the mid-≈1950s.
Incoloy is a nickel ferrochrome alloy designed for oxidation and carbonation at e<levated temperatures.Incoloy alloy has many kinds: common such as Incoloy800,< Incoloy800H, Incoloy800HT, Incoloy825, Incoloy840, Incoloy901, Incoloy925, <Incoloy20, Incoloy330, Incoloy 25-6mo, etc.The alloy contains a small amou✔nt of the metallic elements molybdenum and copper.In reductive acid and oxidizing acid, it has good corrosion resistance, as well as $good resistance to stress corrosion cracking, pitting and crevice corrosion.It has exc&ellent corrosion resistance to sulfuric acid and phosphoric acid.The alloy ha s good cold and hot working properties and is easy to b≥e formed and welded.The main products of this alloy are rods, tubes, plates, strips, wires &and forgings, etc. It is mainly used in the chemical, petrochemical, nuclear ←and rare metal refining industries.
Overview of Nimonic75 (N06075):
Nimonic 75 (N06075) Nickel-based alloy is a nickel-chromium alloy with extremely low titanium and iron content and excellent high temperature performance. The alloy is added w₩ith elements different in the size of the base metal atom (chromium, tungsten, molyb¥denum, etc.) to cause distortion of the matrix metal lattice, and an e≠lement (such as cobalt) which can reduce the stacking fault energy of the alloy✘ matrix and the addition can slow the diffusion of the m™atrix element. The elements of the rate (tungsten, molybdenum, etc.) to strengthen the↓ matrix.

1. Precipitation strengthening: Nimonic 75 precipitates the second phase (γ', &♥gamma;", carbide, etc.) from the supersaturated s↑olid solution by aging treatment, so that the strengthening alloy &gamma♦;' phase is the same as the matrix, which is a face-centered cubic £structure. The matrix constant is close to the matrix and coherent with the crystal. Th≠erefore, the γ phase can be uniformly precipitated in the form of fine particles in th<e matrix, which hinders the dislocation motion and produces a significant strengthening effect. Th∞e γ' phase is an A3B type intermetallic compound, and A represents Nickel, cobalt, B represents aluminum, titanium,' niobium, tantalum, vanadium, tungsten, and chromium, moly©bdenum, iron can be either A or B. The typical γ' phase in a nickel-based alloyγ is Ni3 (Al, Ti). The strengthening effect of the γ' phase can be enhanced bΩy:
(1) increase the number of γ' phases;
(2) Having a suitable mismatch between the γ' phase and the matr÷ix to obtain a strengthening effect of coherent distortion;
(3) Adding elements such as yttrium and lanthanum to incre≈ase the anti-phase boundary energy of the γ' phase to improve its ability to resist dislocation cutting;
(4) Adding elements such as cobalt, tungsten, and molybdenum to increase the strengthφ of the γ phase. The γ" phase is a body-ce"ntered tetragonal structure, and its composition is Ni3Nb. Because of the large mismatch between αthe γ" phase and the matrix, it can cause a large degree of coherent distortion, so t"hat the alloy obtains a high yield strength. However, when it exceeds 700 ° C, the ©strengthening effect is significantly reduced. Coba©lt-based superalloys generally do not contain a gamma pha¶se but are reinforced with carbides.
2, grain boundary strengthening: Nimonic 75 at high temperatures, the grain boundary of the alloy φis a weak link, the addition of trace amounts of boron, zircαonium and rare earth elements can improve the grain boundary strength. This is because the rare earth element can purify the grain boundaδry, and the boron and zirconium atoms can fill the≈ grain boundary vacancies, reduce the grain boundary diffusion rate during the creep process, inhiλbit the grain boundary carbide accumulation and promote the grain boundary sec♦ond phase spheroidization. In addition, the addition of an approprγiate amount of niobium to the cast alloy can also improve the strengthΩ and ductility of the grain boundaries. It is also possible to form 'chain-like carbides at the grain boundaries by heat treatment ®or to cause bending grain boundaries to improve plasticity and strength.

Shanghai haosteel Co., Ltd. Nimonic 75 (N06075) nickel-base©d alloy manufacturing process and characteristics:
1. Nimonic 75 (N06075) nickel-based alloys contain no or less aluminδum and titanium superalloys, and are generally smelted in an elec'tric arc furnace or a non-vacuum induction furnace. When high-temperature alloys© containing aluminum and titanium are smelted in the atmosphere, e₹lemental burning is difficult to control, and gas an♣d inclusions are more intensive, so vacuum smelting should be used. In order →to further reduce the content of inclusions, improve the distribution o♥f inclusions and the crystal structure of the ingot, a double process combining smelti ng and secondary remelting may be employed. The main means of smelting are electric arc furnace, ✔vacuum induction furnace and non-vacuum induction furnace; the main means of remelting♠ are vacuum self-consumption furnace and electroslag furnace.
2. Solid solution strengthened alloys and alloy ingots containing aluminum and tit∞anium (the total amount of aluminum and titanium is less than about 4.5%) can be foλrged blanks; alloys containing aluminum and titanium are♠ generally extruded or rolled. The billet is then hot rolled into a material, and some products need to be further col÷d rolled or cold drawn. Larger diameter alloy ingots or cakes are forged with a hydraulic ≥press or a fast forging hydraulic press.
3. Alloys with high degree of alloying and non-deformation are currentl≥y widely used for precision casting, such as casti♠ng turbine blades and guide vanes. In order to reduce or eliminatγe grain boundaries perpendicular to the stress axis in the cast alloy and to reduce or$ eliminate looseness, a directional crystallization ✘process has been developed in recent years. This process is to grow crystal grain♥s in a crystal direction during solidification of the alloy to obtain paral¥lel columnar crystals without lateral grain boundaries. The &primary process condition for achieving directiona₩l crystallization is to establish and maintain a sufficiently large axia¶l temperature gradient and good axial heat dissipatioβn conditions between the liquidus and the solidus. In addit↑ion, in order to eliminate all grain boundaries, it is also nece÷ssary to study the manufacturing process of single crysta¶l blades.
4. Powder metallurgy process, mainly used to produce precipitation-strengthened and oxide d≠ispersion-strengthened superalloys. This process allows for plasticity and even superp'lasticity of cast superalloys that are generally indeformable.
5. The performance of the comprehensive treatment of superalloys is closely r elated to the microstructure of the alloy, and the microstr&ucture is controlled by metal heat treatment. Superalloys generally require he♦at treatment. Precipitation-strengthened alloys are usually €solution treated and aged. The solid solution strengthened alloy is only subject↓ed to solution treatment. Some alloys are subjected πto one or two intermediate treatments before aging. The solution treatment is fir←stly to dissolve the second phase into the alloy matrix so that the strengthening phase such as & gamma;, carbide (cobalt-based alloy) is uniformly precipita'ted during the aging treatment, and secondly, in order to obtain a ₹suitable grain size to ensure high temperature creeαp. And lasting performance.
6. The solution treatment temperature is generally 1040 to 1220 °↑;C. Currently widely used alloys are treated with intermediate treatment at 1050 to 1100 &d∏eg;C before aging treatment. The main effect of the intermediate treatment is t o precipitate carbides and γ films at the grain bounda₩ries to improve the grain boundary state. At the same time, some alloys also precipitate some &✘gamma; phases with larger particles and form a reasonable mλatch with the fine γ phases precipitated duriσng aging treatment. The purpose of the aging treatσment is to uniformly precipitate the γ phase or the carbide (cobalt♣-based alloy) to increase the high temperature strength, and the aging treatment tempe®rature is generally 700 to 1000 ° C.
