The application research of new materials in the field of automobile forging is an important research direction, aiming to improve the performance of automobile forging, reduce the cost, and meet the requirements of environmental protection and sustainable development. The following are some main aspects of the application research of new materials in the field of automotive forgings manufacturing: Ultra-high strength materials: automotive focus on lightweight design, ultra-high strength materials such as high-strength steel, magnesium alloy and aluminum alloy are widely used in the manufacturing of automotive forgings. These materials have high strength and stiffness, which can reduce the weight of parts and improve the fuel efficiency and performance of the entire vehicle. Deformable toughening materials: In order to improve the impact resistance and toughness of automotive forgings, researchers are exploring the use of new deformable toughening materials. For example, materials such as high-strength low-alloy steel (HSLA) and austenitic recrystallized steel (TRIP) have good ductility and energy absorption capacity, which can achieve more plastic deformation and continuous opening of forgings during the stress process. Composite materials: Composite materials in automotive forgings, such as carbon fiber reinforced composite materials (CFRP) and glass fiber reinforced composite materials (GFRP), have high strength, light weight, corrosion resistance and other characteristics. They can be used to manufacture high-performance automotive parts, such as body structures and chassis components, to improve the performance and safety of the entire vehicle. New functional materials: In addition to traditional structural materials, researchers are also working on the development of new functional materials, such as shape memory alloys, superalloys and high-wear materials. These materials can be used to manufacture automotive forgings with special functions, such as shape memory springs, high-temperature and wear-resistant engine parts, etc., to meet specific engineering needs. Advanced manufacturing technology: The application of new materials also requires the corresponding advanced manufacturing technology to achieve. For example, powder metallurgy technology, 3D printing technology and heat treatment technology are widely used in the manufacturing process of automotive forgings to achieve higher material properties and parts accuracy. Research on the application of new materials in the field of automotive forgings manufacturing aims to develop automotive parts with better performance, lighter weight and more environmentally friendly to meet the requirements of the automotive industry for efficiency, safety and sustainable development. This requires comprehensive consideration of the mechanical properties, processing properties and economic feasibility of the material, and through in-depth research and test verification to promote the application and development of new materials.
