Abstract
AM-SC1TM is a high temperature Mg alloy that was originally developed as a sand casting alloy for automotive powertrain applications. In order to be truly competitive in critical automotive applications magnesium alloys need to have properties that are similar to or better than aluminium alloy counterparts and they need to be readily manufacturable. AMSC1 is suitable for both sand-casting and permanent-mould casting with properties that have been proven for both the AVL Genios LE and the USCAR lightweight magnesium engine projects. This paper describes the interrelationship between the microstructure and the mechanical properties of AM-SC1. The microstructural features contributing to the creep resistance are both inter-and intra-granular in nature and are on length scales from nanometres to micrometres. The creep behaviour at 150°C and 177°C is diffusion controlled with any contribution from the grain boundaries being negligible.
