Brittle fracture is one of the important factors that affects automotive safety. To prevent this problem, attention should be paid to the selection and control of material, process and equipment.
Firstly, selecting suitable materials is crucial. Modern automotive components require materials with high strength, toughness and durability. Poor quality materials can easily lead to cracks or brittle fractures in forging production. Therefore, stable and reliable steel should be selected as the primary material.
Secondly, strict control of processes and equipment is required. For example, during forging, temperature and speed need to be controlled to ensure the forming quality of forgings. In heat treatment, relevant regulations should be strictly followed to ensure the mechanical properties of forgings are not damaged. Regular maintenance and repair of equipment is also necessary to ensure good working condition.
A case study from an automotive forging plant is used to illustrate how to prevent brittle fracture of forgings. Brittle fracture occurred in the crankshaft assembly during its use due to poor material quality and improper heat treatment. The plant optimized material selection and heat treatment processes, and carried out regular maintenance and repair of equipment to ensure the quality and stability of forgings, and prevent brittle fracture problems from happening again.
In conclusion, preventing brittle fracture problems in automotive forging requires attention and control from various perspectives. Only by selecting high-quality materials, controlling strict processes and equipment, can this problem be avoided as potential threats to automotive safety.
