Metallographic structure of Inconel 625

625 is a face-centered cubic lattice structure. When kept at about 650℃ for a long enough time, carbon particles and unstable quaternary phase will be precipitated and will be transformed into a stable Ni3(Nb,Ti) orthorhombic lattice phase. After solid solution strengthening, the molybdenum and niobium components in the nickel-chromium matrix will improve the mechanical properties of the material, but the plasticity will be reduced.

Corrosion resistance of Inconel 625

Alloy 625 shows excellent corrosion resistance in many media. It has excellent resistance to pitting, crevice corrosion, intergranular corrosion and erosion in chloride media. It has good resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid, etc., and also has alkali and organic acid corrosion resistance in oxidation and reduction environments. Effective resistance to chloride ion reductive stress corrosion cracking. There is almost no corrosion in seawater and industrial gas environments, and it has high corrosion resistance to seawater and salt solutions, even at high temperatures. No sensitivity during welding. It is resistant to carbonization and oxidation in static or circulating environments, and is resistant to corrosion by chlorine-containing gases.

3D printing Inconel alloy In625 powder material application

High-temperature alloy refers to a type of alloy material that uses iron, nickel, and cobalt as the matrix, and can work for a long time at a high temperature above 600 ℃ and a certain stress; and has high high temperature strength, good oxidation and corrosion resistance, Good fatigue performance, fracture toughness and other comprehensive properties. Inconel625 is a single austenitic structure, which has good structural stability and reliability at various temperatures. Based on the above performance characteristics, and the alloying degree of Inconel625 is relatively high, it is also called "super alloy" and is widely used. It is an important material used in aviation, aerospace, petroleum, chemical industry, and ships. According to the matrix elements, Inconel625 is divided into iron-based, nickel-based, cobalt-based and other Inconel625. The service temperature of iron-based Inconel625 can generally only reach 750~780℃. For heat-resistant parts used at higher temperatures, nickel-based and refractory metal-based alloys are used. Nickel-based Inconel625 occupies a particularly important position in the entire Inconel625 field. It is widely used to manufacture aviation jet engines and the hottest parts of various industrial gas turbines. If the endurance strength of 150MPA-100H is taken as the standard, and the maximum temperature that nickel alloys can withstand is >1100℃, while nickel alloys are about 950℃, and iron-based alloys are <850℃, that is, nickel-based alloys are correspondingly higher than 150℃ to Around 250°C. So people call nickel alloy the heart of the engine. In advanced engines, nickel alloys have accounted for half of the total weight. Not only the turbine blades and combustion chambers, but also the turbine discs and even the compressor blades of the latter stages have begun to use nickel alloys. Compared with ferrous alloys, nickel alloys have the advantages of higher working temperature, stable structure, less harmful phases, and greater resistance to oxidation and corrosion. Compared with cobalt alloys, nickel alloys can work at higher temperatures and stresses, especially in the case of moving blades.

The above-mentioned advantages of nickel alloys are related to some of its outstanding properties. Nickel is a face-centered cube with very stable structure, and no allotrope transformation occurs from room temperature to high temperature; this is very important for the selection of the matrix material. As we all know, the austenitic structure has a series of advantages over the ferrite structure.

Nickel has high chemical stability. It hardly oxidizes below 500 degrees, and is not affected by warm air, water and some salt solutions at school temperature. Nickel dissolves very slowly in sulfuric acid and hydrochloric acid, but dissolves very quickly in nitric acid.

Nickel has great alloying ability, even adding more than ten kinds of alloying elements does not appear harmful phases, which provides potential possibilities for improving various properties of nickel.

Although the mechanical properties of pure nickel are not strong, the plasticity is excellent, especially the plasticity changes little at low temperature.

Overview of 3D printing Inconel alloy In625 powder

Nconel625 is an alloy grade with a density of 8.4g/cm3 and a melting point of 1290-1350°C. It has excellent resistance to inorganic acid corrosion and has excellent corrosion resistance to various corrosive media in a redox environment.

625 has a face-centered cubic lattice structure. When kept at about 650℃ for a long enough time, carbon particles and an unstable quaternary phase will be precipitated and transformed into a stable Ni3(Nb,Ti) orthorhombic lattice phase. After solid solution strengthening, the molybdenum and niobium components in the nickel-chromium matrix will improve the mechanical properties of the material, but the plasticity will be reduced.
