摘要：
Magnesium alloys show promise for application in formed components where weight saving is an advantage. lit most instances forming is carried out at elevated temperatures. However there at the considerable gains to be had if forming can be carried out under ambient conditions. The present article outlines some of the difficulties that lie in the way of achieving this objective. The underlying metallurgical characteristics of the issues are considered and means for overcoming them are discussed. It is concluded that a combination of microstructure awl texture control remains a promising strategy.
