The performance and reliability of motorcycle are severely tested under high temperature environment, and magnesium alloy forging, as one of the key components of motorcycle, is particularly important to evaluate the performance and performance under high temperature conditions.
First, let’s take a look at the performance of magnesium alloy forgings in high temperature environments. Magnesium alloy has low density, high specific strength and excellent thermal conductivity, so it is widely used in high temperature working areas such as engines, exhaust systems and transmission components in motorcycles. In high temperature environment, magnesium alloy forgings show good oxidation resistance, can maintain low coefficient of thermal expansion and high strength, so as to ensure the reliability of motorcycles under high temperature conditions.
However, there are still some potential problems in magnesium alloy forgings under high temperature environment, which need to be evaluated and improved. The first is the evaluation of antioxidant properties. Magnesium alloy is easy to react with oxygen to form magnesium oxide and surface oxide layer at high temperature. This results in a decrease in the strength and reliability of the material. Therefore, it is necessary to use surface coating or appropriate protective measures to improve the oxidation resistance of magnesium alloy forgings, and to evaluate it by experiment and test means.
The second is the thermal stability assessment of the material. Under high temperature working environment, magnesium alloy forgings may suffer from creep, thermal fatigue and grain growth, which affect their mechanical properties and reliability. Therefore, it is necessary to evaluate the thermal stability of magnesium alloy forgings and determine their durability and life by high temperature experiments and simulations.
In addition, the strength and stiffness of magnesium alloy forgings at high temperatures also need to be evaluated. Since high temperature will cause the plasticity and strength of the material to decline, the load and vibration of the motorcycle in the high temperature environment may cause deformation and rupture of magnesium alloy forgings. Therefore, tensile, compression and fatigue tests are needed to evaluate the mechanical properties and reliability of magnesium alloy forgings under high temperature conditions.
To sum up, the performance and performance evaluation of motorcycle magnesium alloy forgings under high temperature environment is an important research area. The reliability and durability of magnesium alloy forgings under high temperature conditions can be effectively evaluated through anti-oxidation treatment, thermal stability evaluation and mechanical performance testing, which provides reference and improvement basis for motorcycle manufacturers, so as to improve the performance and reliability of motorcycles under high temperature environment.
