Paper Title:
Microstructure and Properties of Sand Casting Magnesium Alloys for Elevated Temperature Applications
  Abstract

It is required of sand casting magnesium used for aircraft industry to be, among others, increasingly creep-resisting. This paper describes microstructure and properties of chosen magnesium sand casting alloys, intended for usage at ambient and elevated temperature. The first part describes the most popular magnesium alloy Mg-9Al-1Zn (AZ91), which, due to the presence of Mg17Al12 phase in its structure, can be used only up to the temperature of ~120°C. The second part describes Mg-5Y-4RE-Zr (WE54) alloy, which can be used at the temperature of up to ~250°C. Unfortunately, its usage is very limited due to high price. The third part characterizes Mg-3Nd-1Gd-Zr (EV31A) alloy, which has properties similar to Mg-5Y-4RE-Zr alloy, but lower price. This paper also discusses the potential applications of these alloys.
