Advances in Magnesium Alloy Development

摘要

Concerted efforts to develop new magnesium die cast alloys have resulted in a series of new alloy compositions which target demanding market segments. In particular, new automotive applications for magnesium have been identified and secured. A prerequisite for success in this market is fulfilment of the specific material properties required by the applications. However, other technical and economic factors also need to be satisfied to make any new alloy an overall market success. The present paper discusses recent alloy developments from a basic material perspective and points out further challenges to future development; the major emphasis is placed on die casting alloys for elevated temperature and crash-sensitive applications. Aspects of development related to the overall value chain are also discussed.
