Exceptional increase in the creep life of magnesium rare-earth alloys due to localized bond stiffening

Adding very small amounts of zinc to magnesium alloys containing rare earth elements dramatically improves their creep life. Here, the authors use first principles calculations and atomic-scale characterization to show that this is due to stiff covalent bonding of zinc and rare earth elements such a...
