Hot Tearing in Magnesium-Rare Earth Alloys

  • Chapter
Magnesium Technology 2016

Abstract

Magnesium-rare earth based alloys generally show good creep resistance at elevated temperatures and are consequently very promising candidates for powertrain applications. However, for magnesium-rare earth alloys to be used in high pressure die-cast components, they also need to have sufficient die-castability. This paper analyses the data from a series of investigations into binary and ternary magnesium-rare earth (RE) based alloys with the REs including La, Ce, Nd, Y and Gd, with an aim to identify alloy compositions that are castable. It is found that Mg-La based alloys are least susceptible to hot tearing whilst alloys containing Nd, Y or Gd tend to have very high hot tearing susceptibility. The hot tearing susceptibility of Mg-RE-Zn and Mg-Al-RE alloys is also addressed.
