What are the common quality problems in the production of aircraft forgings?
Aircraft forgings can have a variety of quality problems during the production process, and the following are some common problems: Porosity: Porosity refers to the gas envelope that forms inside or on the surface of the material. Pores are usually caused by the presence of gas in the raw material or the introduction of gas during the melting process. The porosity has a great influence on the strength and reliability of forged parts. Inclusions: Inclusions refer to foreign bodies in forgings, such as metal, dust, sand, etc. These inclusions may reduce the strength and durability of forgings. Excessive deformation: Excessive deformation means that the forging is subjected to excessive pressure or tension during the forging process, resulting in distortion or deformation of the shape. This may reduce the dimensional accuracy and strength of the forgings. Mismatch or dislocation: Mismatch or dislocation refers to the geometry of the forging does not match or misalign with the design requirements. This can result in parts not being able to be installed or used, affecting the performance of the entire aircraft system. Crack: A crack is a crack or crack that forms in the forging. Cracks may be caused by excessive stress, uneven cooling, or heat treatment problems. Cracks have a serious effect on the strength and reliability of forgings. Metal fatigue: Metal fatigue refers to the damage caused by the gradual damage of metal materials under the stress cycle for a long time. This can result in reduced life and reliability of forgings. In order to avoid these quality problems, aircraft forgings require strict quality control and non-destructive testing during production to ensure that they meet design and safety requirements.
