This paper describes the application of hot forging in aerospace field and discusses the challenges. Hot forging has an important position in the aerospace field, which can meet the requirements of high strength, high reliability and light weight. However, with the continuous development of aerospace technology, hot forging forging is also facing some challenges, including material properties, production process and quality control requirements. This article will analyze these challenges and propose some solutions and development suggestions.
The aerospace sector has extremely high demands on material properties, requiring conditions that can withstand extreme environments and high stresses. As an important metal processing method, hot forging has been widely used in aerospace field. Through the hot forging process, forgings with good mechanical properties, corrosion resistance and fatigue life can be obtained to meet the needs of key components such as structural parts and engine parts of aerospace spacecraft.
Application of hot forging in aerospace field
Aero engine parts: Hot forging parts play an important role in the manufacture of aero engine parts. For example, key components such as turbine disc, compressor disc and combustion chamber shell are often produced by hot forging process to meet the requirements of high temperature, high pressure and high speed working environment.
Aerospace structural parts: Hot forging parts can also be used for aerospace structural parts manufacturing, such as fuselage frame, wing beam edge strip, landing gear, etc. These structures need to have high strength and stiffness to withstand various loads and stresses during flight.
The challenge of hot forging in the aerospace field
Material performance requirements: The aerospace field has very strict material performance requirements, including high strength, high toughness, corrosion resistance and so on. Hot forging forgings require the selection of suitable materials and the optimization of heat treatment processes to meet these performance requirements.
Production process control: The control of hot forging process parameters is very important for forging quality. Improper control of temperature, deformation rate, deformation degree and other parameters may lead to cracks, deformation and other defects. Therefore, it is necessary to precisely control the parameters of hot forging process to ensure the stable and reliable quality of forging parts.
Quality control and inspection: The defect tolerance of forgings in the aerospace sector is very low, so the quality control and inspection of hot forging forgings is an important challenge. It is necessary to use advanced non-destructive testing technology, such as ultrasonic testing, eddy current testing, etc., to ensure that the internal defects of the forging are minimized.
Solutions and development suggestions
Enhanced material development: Continuous research and development of new materials to develop higher performance hot forging materials to meet the stringent requirements of the aerospace sector.
Process optimization and intellectualization: Through the introduction of advanced numerical simulation technology, the hot forging process parameters are optimized to achieve accurate control of the process. At the same time, combined with artificial intelligence technology, the establishment of intelligent hot forging production line, improve production efficiency and product quality.
Strengthen quality control and testing: The use of advanced non-destructive testing technology and online monitoring system to achieve the whole process of hot forging quality control and testing to ensure the stability and reliability of product quality.
Hot forging has important application value in aerospace field, which can meet the requirements of high performance and high reliability. However, with the continuous development of aerospace technology, hot forging forging still faces a series of challenges. By strengthening the efforts of material research and development, process optimization and intelligence, and strengthening quality control and inspection, the application and development of hot forging forgings in the aerospace field can be further promoted.
