Additions of rare-earth elements (including Sc and Y) to Mg alloys are known to improve their creep resistance and high temperature stability especially when Mn is also present [1]. The basic tool to understand and to control the behaviour of any given material system is the underlying phase diagram. Unfortunately in the case of Mg-Mn-Y only little experimental information is known. The use of computational thermochemistry to derive optimised amounts and processing conditions is a modern way to obtain alloys with better properties while minimising the amount of time and money needed.

In this contribution, a complete view of this ternary system will be given and promising compositions for further investigations will be discussed.
