Innovative magnesium alloys corrosion

Since the corrosion performance of a metal is determined primarily by its chemical composition and microstructure, an understanding of the metallurgical effects on corrosion is critically essential. Part II considers the role of typical microstructures and alloying elements of Mg alloys in corrosion. Metallic glass Mg alloys and some other innovative magnesium alloys are also discussed for their interesting atypical compositions or microstructures. This part provides an extension and development of the fundamentals presented in Part I. 

Abstract This chapter deals with the corrosion performance of innovative or unconventional magnesium (Mg) alloys. It considers, on the one hand, all Mg alloys that have an unusual microstructure and/or composition mostly as a result of extreme processing conditions and, on the other hand, the innovative concepts that are used to improve the corrosion performance of conventional alloys. The available literature is reviewed and the specific influences of the microstructure and/or composition on corrosion behaviour is discussed and general possibilities to improve corrosion resistance of these alloys are highlighted.
