Problems solved by technology

However, due to the close-packed hexagonal crystal structure of magnesium, the plastic deformation ability of magnesium alloys is poor, so most of the magnesium alloy products are realized by casting process.
Plastic processing of magnesium alloys at room temperature is relatively difficult, and the residual stress after hot processing is difficult to eliminate, which has an adverse effect on the production and subsequent processing of large-size or high-precision profiles or parts
