Creep Response of a Zn Containing Mg-Nd-La Alloy

  • Chapter
Magnesium Technology 2015

Abstract

A significant improvement in creep resistance was achieved by adding Zn to a Mg-Nd-La alloy. Such an improvement is indicated by an order of magnitude reduction in minimum creep rate by and maintaining remarkably low creep-strain for prolonged duration compared to the non-Zn containing alloy. Addition of Zn resulted in the formation of high number density of fine scale γ” precipitates which presumably enhanced the load bearing capacity of Mg-Nd-La-Zn alloy. Observation of dislocation substructures further revealed that both intragranular precipitates as well as the interdendritic phase retarded dislocation motion.
