Research Progress of Mg alloy Semisolid Forming

Firstly, the background of magnesium alloys semi-solid forming was briefly introduced, and then the present status of magnesium alloy semi-solid forming technology was reviewed from the four fields, including alloy designing, semi-solid forming technology, semi-solid forming under external field treatment and semi-solid simulation of Mg alloy. then, in the past decades of research results: magnesium alloy corrosion resistance increase, obvious grain size, size is more uniform, the preparation of the fine equiaxial recrystallization organization of semi-solid slurry, obtain better mechanical properties, to forecast the product defects, implements the process optimization. The semi-solid process of magnesium alloy is further improved and innovated, which is of great significance to the development of magnesium alloy, Finally, the future development direction of semi-solid forming of magnesium alloys is prospected.
