What are the advantages of aircraft forgings compared to other manufacturing processes (such as casting, machining, etc.)?
Compared with other manufacturing processes (such as casting, processing, etc.), aircraft forgings have the following advantages: strength and durability: forgings are usually made of high-strength metal materials, and after forging, the crystalline structure will be improved, making the forgings have high mechanical properties, such as tensile strength, yield strength and impact toughness. This enables aircraft forgings to withstand high loads and stress under complex working conditions, with a long service life. Dimensional accuracy and geometric complexity: The forging process can achieve high-precision dimensional control, because in the forging process, by controlling the geometry of the forging die and the hammer force, the size and shape errors of the forging can be effectively controlled. At the same time, forging can also produce forgings with complex geometric shapes to meet the needs of aircraft structures for complex shapes, improve the design freedom and product reliability. High material utilization rate: Compared with other manufacturing processes, the material utilization rate of forgings is higher. In the forging process, the plastic deformation of the material through the forging die, almost no shearing and cutting of the material, so the waste of the material can be minimized. This is particularly important in the field of aviation, where materials tend to be expensive. Metal fluidity and structural consistency: During the forging process, due to the plastic deformation of the metal under high temperature stress, the metal fluidity can be enhanced, which is conducive to improving the organization and performance of the forging. At the same time, forging can also improve the structural consistency of forgings, reduce internal defects, and improve the consistency of mechanical properties. It is important to note that aircraft forgings are not a complete technological replacement for other manufacturing processes, and different manufacturing processes may have more suitable applications in specific situations. Choosing the right manufacturing process depends on the specific requirements, objectives and economic benefits of the product.
