Aluminum forging is one of the important components of motorcycle, and heat treatment is the key to improve the performance of motorcycle aluminum forging. This paper will introduce in detail the effect of heat treatment of aluminum forgings on the performance of motorcycles.
First, the type of heat treatment of aluminum forgings
Common types of heat treatment of aluminum forgings include solution treatment, aging treatment, hot processing tempering treatment and isothermal quenching treatment. Among them, solution treatment and aging treatment are the two more commonly used heat treatment methods.
- Solution treatment
Solution treatment is to heat the aluminum forgings to a certain temperature, so that the multiphase structure reaches thermal equilibrium, and is kept at this temperature for a period of time, and then quickly cooled. This method can eliminate the residual intergranular stress and improve the plasticity, toughness and electrical conductivity of the material. - Aging treatment
Aging treatment is on the basis of solid solution treatment, continue to keep aluminum forgings at a certain temperature for a certain time after natural cooling. After aging treatment, aluminum forgings not only have excellent strength and corrosion resistance, but also maintain good plasticity.
Second, the influence of heat treatment of aluminum forgings on the performance of motorcycles - Improve the strength of aluminum forgings
After solution treatment and aging treatment, the strength of aluminum forgings is improved. Solution treatment can improve the plasticity and toughness of aluminum forgings, eliminate the residual stress and increase the strength of materials. Aging treatment can make the crystals inside the aluminum forgings reach a more orderly state, and form more uniformly dispersed nanoparticles, further improving the strength and hardness of the material. - Improve the corrosion resistance of aluminum forgings
Through solid solution treatment, the original large precipitates of aluminum forgings and a small amount of solute present in the microstructure can be replaced into the solid solution, so that the characteristics of different dissolution temperatures of each phase can further promote the disposal of materials with each other, and thus improve the corrosion resistance of materials. - Improve the hardness and wear resistance of aluminum forgings
By isothermal quenching treatment, the hardness and wear resistance of aluminum forgings can be greatly improved. Isothermal quenching is a heat treatment method that is maintained at a high temperature for a certain time and then cooled rapidly. Through the superpressure applied, the microstructure of the material is redistributed, which enhances the uniformity of the sheet elements and distribution, and also improves its folding resistance, so as to further optimize the strength and hardness of aluminum forgings.
In short, methods such as heat treatment of aluminum forgings are key steps to improve the performance of motorcycles. Through heat treatment, targeted optimization can be carried out for different differences, and the effect of effectively improving the safety, stability and durability of motorcycles can be achieved. In the heat treatment process, it is necessary to fully grasp the theoretical knowledge of heat treatment, and according to its characteristics combined with actual material characteristics, continuous testing and innovation, in order to achieve the best program and application practice.
