Abstract
This chapter gives an overview of magnesium alloys with the emphasis on aerospace applications. The strengthening mechanisms, physical metallurgy principles, effects of alloying elements, conventional processing techniques, recent advancements in alloy development and processing are briefly discussed in the following sections. The mechanical properties, corrosion behaviour of aerospace castings and wrought alloys are presented and commented upon in detail. Recent trends in corrosion protection techniques and applications in national and international aerospace projects are presented at the end.
