Alloy2000 superalloy is a high-performance material with excellent high temperature resistance and corrosion resistance, which is widely used in aerospace, petrochemical, metallurgy, chemical industry and other fields.
This article will introduce in detail the material, chemical composition, hardness, density, heat treatment, mechanical properties, mechanical properties, application fields and welding process of alloy2000 superalloy.
1. Material and chemical composition.
Alloy2000 superalloy is mainly composed of aluminum, nickel, molybdenum, titanium and other elements, and its chemical composition is as follows:
Aluminium (AL): 20%-2.9%
Nickel (Ni): 940%-96.0%
Molybdenum (Mo): 20%-3.0%
Titanium (Ti): 015%-0.25%
2. Hardness and density.
The hardness of Alloy2000 superalloy is HB 150 (room temperature, quenched) and the density is 820g/cm³
3. Heat treatment.
Alloy2000 superalloy can be heat treated in two ways: solution and aging.
The solution treatment temperature is between 900 -1100 and the time is 1-4 hoursThe aging temperature is between 620 and 760 for 8-24 hours.
After proper heat treatment, the strength and toughness of the alloy can be improved.
Fourth, mechanical properties.
The tensile strength of Alloy2000 superalloy is about 550MPa at room temperature, the yield strength is about 240MPa at room temperature, and the elongation is about 40% at room temperature.
In high temperature environments, its strength and toughness can still remain stable.
5. Mechanical properties.
Alloy2000 superalloy has good corrosion resistance, wear resistance and heat resistance, and can still maintain a certain strength and toughness in a high-temperature environment, so it is widely used in aerospace, petrochemical, metallurgy, chemical industry and other fields.
Sixth, the field of application.
Because alloy2000 superalloy has good corrosion resistance, wear resistance, high temperature resistance and other characteristics, it is widely used in the manufacture of high-temperature, high-pressure and strong corrosive media in pneumatic propulsion systems, gas turbines, petrochemical industries, nuclear energy fields and other fields.
7. Welding process.
Alloy2000 superalloy can be welded by TIG, MIG, PAW, EBW and other welding methods, among which TIG welding is the most commonly used one.
Before welding, the alloy needs to be pre-heated to relieve internal stress and ensure the quality of welding.
Summary. As a high-performance material, alloy2000 superalloy has a wide range of application prospects in aerospace, petrochemical, metallurgy, chemical industry and other fields.
After proper heat treatment, its strength and toughness can be improved, and it still has good corrosion resistance, wear resistance, high temperature resistance and other characteristics in high temperature environments.
In practical application, it is necessary to choose the appropriate welding method and process according to the specific situation to ensure the welding quality.
