Alloy material: high temperature alloy material


Release time:

2022-03-24

High-temperature alloy materials, high-temperature alloy materials with excellent oxidation resistance and hot corrosion resistance in aero engines, automobile engines, gas turbines, nuclear power, petrochemical and other fields are widely used. Characteristics, the so-called high temperature alloy, that is, a kind of alloy that can work for a long time under the action of high temperature above 600 ℃ and certain stress. Compared with traditional metals, high-temperature alloy materials have high temperature and high strength in performance, good oxidation resistance and hot corrosion resistance, good fatigue resistance, fracture toughness and good elastic plasticity.

Characteristics

The so-called high temperature alloy, that is, a kind of alloy that can work for a long time under the action of high temperature above 600 ℃ and certain stress. Compared with traditional metals, high-temperature alloy materials have high temperature and high strength in performance, good oxidation resistance and hot corrosion resistance, good fatigue resistance, fracture toughness and good elastic plasticity.

Classification

High temperature alloys are generally divided into three ways: according to the type of matrix elements, according to the type of alloy strengthening and according to the material forming method.

Preparation process

High-temperature alloy products are mainly non-standardized, so the production process is more complex, but basically can be divided into three steps: melting, casting and hot processing, the powder metallurgy industry will replace the casting process for hot pressing.

Application

Superalloys are widely used in aero-engines, automobile engines, gas turbines, nuclear power, petrochemical and other fields due to their excellent oxidation resistance and hot corrosion resistance.

In many application fields, aerospace still occupies a more important position, accounting for 55% of the total demand, followed by the power industry, accounting for 20%.

aero engine

High-temperature alloys have been used in aero-engines since their birth. In modern aero-engines, high-temperature alloy materials are mainly used in four hot-end components: combustion chamber, guide chamber, turbine blade and turbine disk, as well as in casing, ring parts, afterburner and tail nozzle.

The research and development of high-temperature alloys in my country started in the 1960 s, forming a unique alloy system, and has made significant progress. Up to now, many production and scientific research units have been established, and they have deformed high-temperature alloys and cast high-temperature alloys. The production base and the production and research base of high-temperature alloy materials.
