Development of Investment‐Casting Process of Mg‐Alloys for Aerospace Applications

Investment casting offers high‐quality castings with good dimensional accuracy, being therefore suitable for aircraft applications. Since commercial ceramic shells react with Mg melts and appropriate inhibitors being not available, magnesium alloys are not widely used in industrial investment‐casting. In order to overcome this situation and enable the aircraft industry to take advantage of the light‐weight properties of magnesium, the process is analyzed within the European FP6 IDEA project, which aims at developing new high‐strength magnesium casting alloys for aeronautic applications.
