Nickel-based alloy is a nickel-based alloy with excellent properties such as high-temperature strength, corrosion resistance, and fatigue resistance. It is widely used in aerospace, energy, chemical industry, medical and other fields. This article will introduce in detail the composition and characteristics of nickel-based alloys.
1. Composition of nickel-based alloy
Nickel-based alloys are alloys composed of nickel and other elements, usually including the following main elements:
1. Nickel
Nickel is the main component element of nickel-based alloys, usually accounting for more than 50% of the alloy composition. Its high-temperature strength, corrosion resistance, fatigue resistance and other properties are one of the important characteristics of nickel-based alloys.
2. Chromium
Chromium is one of the commonly used alloying elements in nickel-based alloys. Its addition can improve the corrosion resistance and oxidation resistance of the alloy. Usually, the chromium content is between 10% and 30%.
3.Molybdenum
Molybdenum is one of the commonly used alloying elements in nickel-based alloys. Its addition can improve the high-temperature strength and corrosion resistance of the alloy. Usually, the molybdenum content is between 2% and 15%.
4. Iron
Iron is the matrix element in nickel-based alloys, and its content is usually less than 10%. The addition of iron can improve the strength and hardness of the alloy and reduce the cost of the alloy.
In addition to the above commonly used alloying elements, nickel-based alloys may also contain other elements, such as titanium, aluminum, niobium, tungsten, zirconium, boron, etc. The addition of these elements can further optimize the performance and application range of the alloy.
2. Characteristics of nickel-based alloys
Nickel-based alloys have the following main characteristics:
1. High temperature strength
Nickel-based alloys have excellent high-temperature strength, and their yield strength and tensile strength can maintain high levels in high-temperature environments. This makes nickel-based alloys widely used in high-temperature environments, such as aerospace engines, petrochemical equipment, nuclear reactors and other fields.
2. Corrosion resistance
Nickel-based alloys have good corrosion resistance and can maintain stable performance in various corrosive media such as acids, alkalis, and salts. This makes nickel-based alloys widely used in chemical industry, marine engineering, oil drilling and other fields.
3. Fatigue resistance
Nickel-based alloys have good fatigue resistance and can be used for long periods of time under high stress cycles without fatigue damage. This makes nickel-based alloys widely used in aircraft, automobiles, mechanical engineering and other fields.
4. Small thermal expansion coefficient
Nickel-based alloys have a small thermal expansion coefficient, making them less likely to deform or crack in high-temperature environments. This makes nickel-based alloys more widely used in high-temperature environments, such as aerospace, petrochemicals, nuclear reactors and other fields.
5. Good high temperature oxidation stability
Nickel-based alloys have excellent high-temperature oxidation stability and can be used for long periods of time in high-temperature and oxidizing environments without oxidative damage. This makes nickel-based alloys more widely used in high-temperature oxidizing environments, such as aerospace, petrochemicals, nuclear reactors and other fields.
