| Abstract Scope |
Since the end of the last millennium, Mg alloys have made inroads into the applications in automotive industries as well as in consumer, computer and communication (3C) applications. Their favourable property profile – high specific strength, good machinability, recyclability – promote increased usage. Still, the full potential of Mg as a structural material has not been achieved. There a number of reasons can be specified:
1. Market issues: Price, protective duties, dependence on the Chinese Mg market, availability etc.
2. Reservation against Mg due to misinterpretation of properties: “magnesium corrodes”, “magnesium burns” etc.
3. Inadequate properties i.e. strength, ductility, corrosion behaviour, crash worthiness etc.
4. Limited number of suitable Mg alloys may restrict wider application of Mg alloys.
5. Life cycle assessment issues.
6. Despite magnesium alloys being in service for almost one hundred years, there is still a lack of knowledge potential of Mg alloys compared with other metallic materials such as steel or aluminium: Design, processing, potential etc. |
