The allowed deformation of magnesium alloy forging
Magnesium alloy forging is a common manufacturing process used to produce components of different shapes and sizes. It is one of the lightest metals and has high strength, which makes it ideal for producing components where durability and light weight are important considerations. The process of forging magnesium alloys involves a combination of heat and pressure to shape the metal into the desired form. The process increases the strength and resistance of the metal while decreasing its ductility. Therefore, it is important to control the amount of deformation of magnesium alloy forging during the process.
The amount of deformation that is allowed in magnesium alloy forging depends on the application of the component, as well as the type of magnesium alloy that is being forged. Generally, magnesium alloys are susceptible to deformation when exposed to high temperatures. Therefore, the tempering temperature needs to be carefully controlled in order to prevent the plastic deformation and maintain the strength and quality of the forged component. For most applications, the allowed deformation of magnesium alloy forging is between 5-10%. However, for higher-load components, the allowed deformation may be limited to 3-5%.
Forging involves high temperatures and pressure and can cause severe deformations if the process is not properly controlled. Therefore, it is important to understand the properties of the specific magnesium alloy that is being forged before attempting the process. This will help ensure that the component is not exposed to temperatures that can cause excess deformation. Additionally, it is important to select the proper shape and size of the component, and to use the correct die and hammering techniques to ensure that the component is not over-forged.
For components intended for vital applications, the allowed deformation of the component must be tightly controlled. This is typically done through non-destructive testing, such as eddy current testing or radiographic testing. These tests can detect any internal and/or external deformations in the component and help determine if the component is suitable for its intended application.
In conclusion, the amount of deformation that is allowed for magnesium alloy forging depends on the application of the component and the type of alloy that is being forged. In general, magnesium alloys become more susceptible to deformation at higher temperatures, so it is important to control the tempering temperature. Components that are intended for vital applications must also be subjected to non-destructive testing in order to verify the absence of deformations. With the proper precautions, magnesium alloy forging can be used to produce highly durable components with light weight.
