Magnesium alloy has the advantages of low density, high specific strength, good electrical and thermal conductivity, etc., and has been widely used in aerospace, automobile, electronics and other fields. Forging is an important magnesium alloy forming process, which can significantly improve the mechanical properties and plastic deformation capacity of magnesium alloys. However, magnesium alloy is prone to cracking, deformation and other defects in the forging process, which affect the quality and performance of the forging. Therefore, it is of great significance to study the relationship between microstructure and mechanical properties of magnesium alloy forgings for optimizing forging process and improving forging quality.
In this paper, magnesium alloy forgings with different forging processes were selected as the research objects. Metallographic analysis and scanning electron microscopy were used to observe the microstructure of the forgings. At the same time, tensile test and hardness test are used to measure the mechanical properties of forgings. The effects of forging process on microstructure and mechanical properties of magnesium alloy forgings were discussed by comparative analysis.
Microstructure analysis
Through metallographic analysis and scanning electron microscope observation, it is found that the microstructure of magnesium alloy forgings with different forging processes is obviously different. Proper forging process can make magnesium alloy forgings obtain fine and uniform grain structure and improve the mechanical properties of the material. The improper forging process may lead to coarse grain, uneven structure and other defects, and reduce the mechanical properties of the material.
Mechanical property analysis
Through tensile test and hardness test, it is found that the forging process has a significant effect on the mechanical properties of magnesium alloy forgings. Proper forging process can improve the tensile strength, yield strength and hardness of magnesium alloy forgings. This is mainly due to factors such as grain refinement, microstructure homogenization and the increase of dislocation density during forging. At the same time, the forging process can also improve the plasticity and toughness of magnesium alloy forgings, and improve its comprehensive mechanical properties.
In this paper, the relationship between microstructure and mechanical properties of magnesium alloy forgings is studied experimentally, and the following conclusions are drawn:
The forging process has significant influence on the microstructure and mechanical properties of magnesium alloy forgings.
Proper forging process can make magnesium alloy forgings obtain fine and uniform grain structure and excellent mechanical properties.
It is important to optimize the forging process for improving the quality and performance of magnesium alloy forgings.
In the future research, the influence of different forging parameters on the microstructure and mechanical properties of magnesium alloy forgings can be further discussed, so as to provide theoretical basis and technical support for the realization of high performance and industrial application of magnesium alloy forgings.
