| Abstract Scope |
Poor cold formability, poor corrosion resistance and high cost of alloying elements are longstanding barriers to the widespread use of Mg. In this talk, we report that both the room-temperature (RT) stretch formability and corrosion resistance of the commercially used pure Mg could be significantly improved by adding trace amounts of Cu and Ca. The significant enhancement in the RT stretch formability is associated with the weakened basal texture and refined microstructure, whereas the substantial improvement in the corrosion resistance is related to the strong Fe-removal ability induced mainly by Ca addition and formation of a protective surface film enriched with Cu and Ca. Owing to the trace amounts of the alloying elements, the resultant alloy also showed excellent thermal conductivity, which was almost two times higher than that of the most commonly used Mg alloy (AZ31). These findings are expected to stimulate the development of high-performance Mg alloys. |
