Creep response and microstructures. a Strain rate vs. time plots show an order of magnitude improvement in the creep life of Mg–Nd–Zn (red) over Mg–Nd (blue) and both differ significantly from Mg (black). Panels b–d are TEM and HAADF-STEM observations for Mg–Nd and Mg–Nd–Zn systems taken at points b–d marked in panel a. BFTEMs in panels b and c show that β′ precipitates (also inset HAADF-STEM along [11\(\bar 2\)0]α) and fine-scale GP zones (arrows), respectively, in Mg–Nd lie on the prismatic planes of hcp-Mg. In case of Mg–Nd–Zn, HAADF-STEM in panel d shows γ″ and γ precipitates lying on both basal and prismatic planes, respectively. e Raw ion maps from atom probe tomography confirms the presence of Zn in γ″ along with Nd. Scale bars in panels b–d are 100 nm, 20 nm, and 20 nm, respectively
