Abstract
Currently most magnesium alloys are based on the Mg-Al system and this system is reasonably well developed. Nevertheless, the alloy system has some disadvantages - while having excellent castability and adequate room temperature mechanical properties Mg-Al alloys show poor creep resistance. This has led to investigations in other magnesium based systems; magnesium forms alloys with a large number of elements and, indeed a number of magnesium systems show good creep resistance. In this work, the Mg-Sn system has been chosen for study.
