Abstract
We use density functional theory calculations to explain why βâ²-long instead of βâ²-short forms during age-hardening process in Mg-Gd alloys. We calculate strain energies and interfacial energies of βâ³, βâ²-short and βâ²-long in Mg-Gd alloys and find that (1) results of strain energies and interfacial energies of βⳠagree well with other theoretical works (2) habit plane of βâ²-long predicted by density functional theory calculations is consistent with experimental observation (3) strain energy is mainly responsible for the formation of βâ²-long instead of βâ²-short in the age-hardening process.
