Description

The creep-strengthening effect of Mn in Mg–Ce alloys has been studied via creep testing and transmission electron microscopy. It appears that α-Mn precipitates may serve as nucleants for the intradendritic heterogeneous nucleation of Mg12Ce precipitates which play a primary role in creep strengthening. The nucleation caused a decrease in the maximum size and a change in the morphology of Mg12Ce precipitates. It was observed that the nucleation and growth of α-Mn and Mg12Ce precipitates are mutually affected by the presence of the other.
