Modeling of Stacking Fault Energy in Hexagonal-Close-Packed Metals by Zhigang Ding, Shuang Li, Wei Liu, Yonghao Zhao

“…In the review, we examine the theoretical background of three normally used models, supercell model, Ising model, and bond orientation model, for the calculation of SFE of hexagonal-close-packed (hcp) metals and their alloys. To predict the nature of slip in nanocrystalline metals, we further review the generalized stacking fault (GSF) energy curves in hcp metals and alloys. …”
