The so-called nickel-based alloy materials are alloys that use nickel as the matrix and can resist corrosion in some media. They are called nickel-based corrosion-resistant alloys. In addition, corrosion-resistant alloys containing more than % nickel and more than % nickel plus iron are customarily called iron-nickel-based corrosion-resistant alloys (see stainless acid-resistant steel).
The alloy (M alloy) produced in the United States in 2008 is the earliest nickel-based corrosion-resistant alloy. The United States began to produce rM-type corrosion-resistant alloys (R) in 2007, and Germany began to produce rM-type corrosion-resistant alloys containing about % of r and about % of M.
In the 1990s, almost all corrosion-resistant alloy grades produced by various countries were produced. Among them, the alloy series with larger output and wider use include r, M, rM, rM and r, rM, with a total of more than ten brands.
Nickel-based alloy material is a kind of high-temperature alloy. High-temperature alloy refers to a type of metal material based on iron, nickel, and cobalt that can work for a long time at high temperatures above ℃ and under certain stress and has a high High temperature strength, good anti-oxidation and anti-corrosion properties, good fatigue properties, fracture toughness and other comprehensive properties.
High-temperature alloys have a single austenite structure and have good structural stability and reliability at various temperatures. Based on the above performance characteristics, and the high degree of alloying of high-temperature alloys, they are also called superalloys , is an important material widely used in aviation, aerospace, petroleum, chemical industry, and ships.
According to matrix elements, high-temperature alloys are divided into iron-based, nickel-based, cobalt-based and other high-temperature alloys. The service temperature of iron-based high-temperature alloys can generally only reach ~℃. For heat-resistant parts used at higher temperatures, nickel-based and refractory metal-based alloys are used. This is what nickel-based alloy materials are.
Nickel-based high-temperature alloys occupy a particularly important position in the entire field of high-temperature alloys. They are widely used to manufacture the hottest components of aviation jet engines and various industrial gas turbines. If MH lasting strength is used as the standard, the temperature that current nickel alloys can withstand is >℃, while nickel alloys are about ℃, and iron-based alloys are <℃, that is, nickel-based alloys are correspondingly higher than ℃ to about ℃. So people call nickel alloy the heart of the engine.
At present, in advanced engines, nickel alloys account for half of the total weight. Not only turbine blades and combustion chambers, but also turbine disks and even later compressor blades have begun to use nickel alloys. Compared with iron alloys, the advantages of nickel alloys are: higher working temperature, stable structure, less harmful phases, and greater ability to oxidize and corrode. Compared with cobalt alloys, nickel alloys can operate at higher temperatures and stresses, especially in moving blade applications.
Specific applications of nickel-based alloy materials: nickel-copper nickel-based alloys that can be deformed have good resistance to seawater corrosion and chemical corrosion, and strong resistance to chloride stress corrosion cracking. This alloy is one of the few that can be used in fluorides. It has good resistance to oxide stress cracking corrosion in hydrofluoric acid and fluorine gas media, such as seawater and salt water environments. It also has very good corrosion resistance in moderately concentrated alkaline and salt solutions. In colder alkaline environments, the alloy is used in weak acid environments such as sulfur and hydrogen fluoride. Nickel-based alloy materials are generally used in aerospace, oil and gas development, petrochemical industry, chemical engineering, electric power industry, environmental protection engineering, automobile industry, marine engineering, electronic industry, electric heating, heat treatment, welding, etc.
