Abstract:

In this paper, the applications of different various plastic deformation processing, such as hot extrusion, rolling and large plastic deformation, on grain refinement of wrought magnesium alloy were reviewed systematically. The high cost of related products caused by low processing speed has been regarded as one of the main factors limiting the development of wrought magnesium alloys. But in the future, this problem can be solved by semicontinuous casting preparation of large size using multioutfield and rapid processing of fine grained magnesium alloys.

Key words: wrought, mechanism, magnesium alloys, grain refinement
