| Abstract Scope |
Although Mg alloys, as the lightest structural alloys, offer significant potential for automotive applications, their applications, particularly sheet products, in automobiles is quite limited since few Mg alloys fulfill the properties and cost requirements of automotive industry. It has been recently shown that twin-roll casting (TRC) can produce low cost, high quality Mg alloy sheets that have comparable or better mechanical properties compared to those of conventional Mg alloy sheets produced by ingot casting and subsequent complicated rolling process. In this presentation, the recent progress in the development of Mg alloys by TRC will be reviewed with particular emphasis on the fundamental aspects such as microstructure and texture evolution and deformation behavior. Also presented will be some examples showing the applications of TRC Mg alloys in automobiles and the author’s own perspective, which would guide future research aimed at improving the properties and broadening the structural applications of Mg alloys. |
