Description

technical field [0001] The invention relates to a magnesium alloy quenching-aging integrated device, which is mainly used for quenching deformed rare earth magnesium alloys with large cross-sectional sizes. Background technique [0002] Magnesium alloys, as the lightest structural metal materials, are increasingly used in aerospace and automotive industries. At present, the amount of cast magnesium alloy is much larger than that of deformed magnesium alloy. The main reason is that cast magnesium alloy has good flow properties and is easy to form, so it is also the largest application field of magnesium alloy. However, traditional cast magnesium alloys have inherent weaknesses, that is, there are many casting defects, low strength, and large performance differences, so they cannot be used as large load-bearing components. Although more precision forming methods have been developed in recent years, However, as a large-scale structural material, the precision and manufacturing...

AI Technical Summary

Problems solved by technology

Unlike aluminum alloys, the research on hardenability of magnesium alloys is very limited. Due to the short development history of magnesium alloys, it is still focused on the development of new alloys. The deformed magnesium alloys for real engineering applications are still very limited, but engineering applications The applied wrought magnesium alloys have relatively good thermal conductivity, such as AZ and ZK alloys, and the hardenability problem has not risen to the level that must be studied

[0005] Many characteristics of magnesium alloys, especially the understanding of the physical and chemical properties of newly developed magnesium alloys are still in their infancy, leading to lagging behind in the development of related technologies for quenching and aging of magnesium alloys, and the development and application of large-scale new magnesium alloys are subject to unprecedented restrictions. Lower yield and higher production costs hinder the production and application of magnesium alloys
